Introduction
WinCHAP is the Windows-based FONIX Computer Hearing Aid Program. This
program makes interfacing FONIX instruments with a computer easy and convenient while providing you with an office management database.
The WinCHAP Office Manager lets you store extensive client, hearing aid, manufacturer, test instrument, and personnel information. This information can be
entered manually or imported from NOAH 3.
The WinCHAP Test Menu lets you to save important measurements made with
your FONIX analyzer or audiometer, eliminating the need for paper files.
WinCHAP has gone through some fairly significant changes since its inception, including 32-bit programming, improved user interface, and greater testing capabilities. Many of these changes came from direct feedback from our
valued customers. In order to further improve WinCHAP’s usability, we invite
you to contact us with any comments or suggestions for improvement at:
support@frye.com.
1.1 Installation
This section describes how to install WinCHAP and upgrade it from an older
version.
1.1.1 Installing WinCHAP
If you are upgrading from version 1.0 through 2.0, read Section 1.1.2 first.
• Close all programs running on your Windows system.
• Insert the CD-ROM into your CD-ROM drive.
• The “Install Program” should begin to run automatically. If it does not,
run “setup.exe.” You can start the setup.exe program from Windows
Explorer or by using the Run feature in the Windows start up menu.
• Let the Install Shield guide you through the installation process.
Note: In some cases, on machines with Windows 95, one of the .dll files being
installed is perceived to be in use. An error message will open. Choosing ignore
allows the installation to continue. Once the installation is finished, restart your
computer. WinCHAP will operate normally.

4 Introduction
WinCHAP User’s Manual
1.1.2 Upgrading from an old version of WinCHAP
If this is an upgrade from version 1.0 through 2.0 of WinCHAP, it will be necessary to perform a few simple tasks in order to make sure all your old data will
be useable with the new version of WinCHAP.
A. Back up existing WinCHAP database files
First, you should back up any WinCHAP database files you may have. The
process of uninstalling WinCHAP shouldn’t delete any database files, but it’s
always a good idea to backup your data before making any big changes.
1. Open WinCHAP.
2. Open the Settings menu and click Database Manager to open it.
3. Look at the bottom of the Database Manager window and find the filename of the current database. See Figure 1.1.2.
4. Open Explorer and locate the database file. Ask your local computer
expert for help if necessary.
5. Right-click on the file name and click copy.
6. Find a secure directory such as “C:\My Documents,” right click on the
directory name, and select “Paste” to save a copy of the database to that
directory. Again, ask your local computer support person for help if necessary.
B. Uninstall current version of WinCHAP
You will need to uninstall the current version of WinCHAP from your computer.
To do this:
1. Press the Start button of your Windows operating system.
2. Select Settings and Control Panel.
3. Select Add/Remove Programs.
4. Find and highlight WinCHAP or WinCHAP 32 in the list of programs.
5. Click the Add/Remove button.
6. The install shield will guide you through the uninstall process. It
should take just a few minutes.
C. Install new version of WinCHAP
You are now ready to install the new version of WinCHAP. See Section 1.1.1 for
instructions.
D. Import WinCHAP database
Import WinCHAP database using the database saved in Step A. See Section 2.3.5.
WinCHAP User’s Manual
Introduction 5
Figure 1.1.2—Database Manager
1.2 Computer Requirements
WinCHAP runs on Microsoft Windows 95, 98, 2000, Me, NT 4.0, and XP. It
needs a Pentium chip or equivalent. You will need at least 32 MB of RAM and
30 MB of free hard disk space for the program to function optimally. Large databases could require an additional 100 MB or more disk space. For best readability, set your monitor to 800 x 600.
1.3 Setup
The RS232 connectors and cable will have come with your FONIX instrument
or with the RS232 package. Insert the ends of the cable into each of the connectors. Attach the 25-pin or 9-pin connector (depending on your serial port)
labeled “COMPUTER” to COM 1 or COM 2 on your computer. Attach the other
connector to your FONIX instrument. See your instrument manual for more
detail.
1.3.1 Adding Communications Ports
In many cases, your computer will only have one COM port that is already
being taken up by your hearing aid programmer. There are a couple of different
solutions to this problem.
6 Introduction
WinCHAP User’s Manual
Most new computers have one or more USB ports. (They look like small rectangular holes on the back of your computer.) If you have one, you can get a
USB to RS232 hub. This is a small box that plugs into the USB port that adds
multiple communications ports onto your computer. You can hook your FONIX
analyzer up to one port, your FONIX audiometer to another, and your programmer to a third.
A cheaper solution, if you have a desktop computer, is to buy an electronics
card with an additional serial port. Ask your local computer expert for help.
1.4 Instrument Requirements
In order to communicate with WinCHAP, your FONIX instrument needs to be
equipped with RS232. The required software versions for each instrument are:
6500-CX
FP40 and FP40-D
FP35
FA-10 and FA-12
7000
4.50 and higher
3.40 and higher
2.0 and higher
all versions
1.10 and higher
Note: WinCHAP may work with earlier software version of the FP40 and 6500CX, but not all functions may be available.
1.5 Registration
If you purchased your copy of WinCHAP, or if you are receiving a free upgrade
from a previous version of WinCHAP, both the serial number and the registration key should be included on the WinCHAP CD-ROM case.
If you ordered a demo copy of WinCHAP in order to evaluate the software
before purchasing it, only the serial number of that copy of WinCHAP was
included. In order to purchase the software and receive the registration key,
please contact us at:

WinCHAP, you will have to use the Database Manager to import your old
data.
• You have a reason to separate your records into categories—for instance,
according to different office branches—you can create new databases in
addition to the default database.
• You have been using the original FONIX CHAP software, and you want to
import the information you have stored there to a WinCHAP database.

Test Menu
The Test Menu is the window from which you can open any WinCHAP test. It is
divided into two sub-windows: the Client-Patient window and the Hearing Aid
window.
The Client-Patient window lists all records in order by client. Any attached
audiometric tests, DSL/NAL tests, or hearing aids are listed under the client
record.
The Hearing Aid window lists all records in order by hearing aid model and
serial number. Any saved hearing aid tests are listed under the hearing aid
record.
There are two ways to get to the Test Menu.
• From WinCHAP’s Main Menu, click Test Menu. This will allow you to
test any client or hearing aid entered in the Office Manager
• From the Office Manager, click Test Menu in the toolbar. This will open
the Test Menu and list only the client or hearing aid displayed in the
Office Manager.
4.1 The Test Menu Display
The Test Menu contains records of all clients, hearing aids, and measurements
saved in WinCHAP. There are two sub-windows: the Client-Patient window and
the Hearing Aid window.
The Client-Patient window lists all records in order by the client attached
to them. Whenever a client has a saved audiometric test, DSL/NAL test, or
attached hearing aid, a PLUS (+) will appear to the left of his name. If you click
it, the client’s record will open and display the attached list of tests and hearing
aids. If the client has an attached hearing aid, that hearing aid listing may have
a PLUS (+) next to it. Click it to open the hearing aid record containing the listing of all tests attached to the aid. See Figure 4.1A.
The Hearing Aid window lists all records in order by the hearing aid attached to
them. It works much like the Client-Patient listing; whenever a hearing aid has a
saved test record, a PLUS (+) will appear to the left of its listing. If you click it,
the hearing aid record will open and display the attached tests. See Figure 4.1B.
Both windows have the same basic format and share the same toolbar.
• The left column of the window contains the Client-Patient and Hearing
Aid icons that are used to switch back and forth between the two subwindows.

Impedance is a measurement of how sound energy flows through the middle
ear. Although FONIX equipment does not measure impedance, if you have performed the measurements with an impedance audiometer, you can store the
data here. When importing data from NOAH 3 (See Chapter 8), any impedance
data saved to the patient’s record will be transferred to this window.

The DSL/NAL-NL1 Module
The DSL/NAL-NL1 test window was designed to help fit non-linear hearing aids
according to the DSL or NAL-NL1 fitting formulas. Both formulas are highly
adaptable and have many different settings that will allow you to fine-tune your
hearing aid fittings.
The University of Western Ontario developed the Desired Sensation Level (DSL)
method of hearing aid fitting. The goal of the DSL method is to make amplified
speech audible. The DSL method differs from many traditional methods; it uses
an SPL-o-gram rather than insertion gain and, when necessary, incorporates 2-cc
coupler measurements made in the sound chamber into the hearing aid fitting.
DSL was originally designed to expedite fitting hearing aids for young children
and to improve the accuracy of those fittings.
The NAL-NL1 fitting formula is the natural non-linear extension to the NALR linear formula that has been dominant in the hearing aid industry for many
years. NAL-NL1 is based on insertion gain measurements, and it takes into
account many factors including the number of channels of the hearing aid,
whether the patient has a binaural or monaural fitting, and even what type of
output limiting is present on the hearing aid.
To enter the DSL/NAL-NL1 test window:
1. Click Test Menu in the Main Menu.
2. Locate the client you want to test. See Section 4.1.3.
3. Select the client’s name in the right column of the Test Menu. This will
bring up the client test selection window.
4. Choose DSL/NAL-NL1 Test.
The DSL/NAL-NL1 test has four windows: The Audiometry window, DSL window, NAL-NL1 window, and the Info window. The Audiometry window is used
to input audiometric information such as thresholds and upper limit values. You
can also use it to perform RECD and REDD transforms or input existing data.
The DSL and NAL-NL1 windows are used for taking real-ear and coupler measurements and compare them to the displayed targets. The Info window records
the date the test is taken, the clinician performing the fitting, and the equipment
used to take the measurements. The DSL 2-cc coupler derivations are also displayed in this window; they are generally used when ordering a hearing aid to
match the patient’s hearing loss.
6.1 General Information
General operations of the DSL/NAL-NL1 test such as opening existing tests,
creating new tests, changing clients, printing results, and saving defaults are
described in this section.

6.2 Audiometry
The first step in a hearing aid fitting is to obtain the patient’s audiometric information. These can include hearing threshold levels (HTL), bone conduction
values, uncomfortable levels (UCL), and audiometric transforms. All of these
measurements can be stored in the Audiometry window. Some values, such as
the UCL and transform values, can be predicted from the patients HTLs and age.
See Figure 6.2.
WinCHAP User’s Manual
The DSL/NAL-NL1 Module 65
Figure 6.2—The Audiometry window
6.2.1 Entering threshold data
There are two ways to enter audiometric data: you can use the graph and your
mouse to “click in” your values, or you can use the numerical tables at the bottom of the window and enter the values manually.
6.2.1.1 To use the assessment graph
1. Enter the Audiometry window by clicking the Audiometry icon in the left
column of the DSL/NAL-NL1 test.
2. Click Settings and select the General tab.
3. Select the Transducer used to make the audiometric measurements. If a
loud speaker was used, also select the Loud Speaker Orientation. This
should also be the orientation that you use for any real-ear measurements.
4. Click Back to close the Settings window.
5. Make sure AC Threshold is selected in the legend to the right of the
Assessment Data graph. It should have a small black check to the left of
the listing.
6. Use your mouse to input the amplitude for each frequency on the graph.
7. Click Save in the toolbar to save the results.
66 The DSL/NAL-NL1 Module
WinCHAP User’s Manual
6.2.1.2 To use the audiometry table
1. Follow steps 1-4 in the previous section.
2. Select the appropriate column in the Audiometric Information table in the
lower half of the Audiometry window.
3. Enter the amplitude data in the boxes corresponding to the appropriate
frequencies. Use your Enter key to move between fields.
4. Click Save in the toolbar to save the results.
6.2.2 Entering/Predicting Upper Limit values
The AC Upper Limit values are defined as the client’s upper limits of comfort.
You can choose to have WinCHAP predict these values, based upon the client’s
age and entered thresholds, or you can enter measured values. WinCHAP uses
the DSL method to make these predictions.
Choose between Predicted or Measured in the Upper Limit box to the right
of the Assessment Data graph. Measured upper limit values are entered in the
same manner as threshold values. See Section 6.2.1.
6.2.3 Entering Bone Conduction values
Bone conduction values are entered in the same manner as threshold values. If
entered, NAL-NL1 uses them in creating measurement targets. DSL does not use
these values.
6.2.4 Performing or Predicting an RECD measurement
The real-ear to coupler difference (RECD) measurement finds the acoustical difference between a 2-cc coupler and your patient’s ear. The DSL and NAL-NL1
formulas take these differences and create realistic coupler target curves. This is
particularly useful when fitting babies and small children who don’t allow you
to take an actual real-ear measurement.
To predict the RECD based on the patient’s age, selected Predicted in the RECD
box in the Audiometry window. The predicted RECD (as well as the predicted
REUR and REDD) values are displayed in column format on the bottom half of
the window. DSL and NAL use different predictions for these transforms in their
fitting formulas; the Settings window lets you set which prediction values are
displayed.
To measure the RECD, select Measured in the RECD box and follow the instructions in the following sections.
6.2.4.1 To perform the coupler measurement
This section describes how to perform the coupler part of the RECD measurement. The procedure is different for the 6500-CX and FP40 than for the FP35
and 7000 analyzers.
The DSL/NAL-NL1 Module 67
WinCHAP User’s Manual
The DSL and NAL methods for performing RECD measurements are slightly
different. DSL recommends performing all RECD measurements using an HA-2
coupler, even when fitting a canal-type aid that would normally be tested with
an HA-1 coupler; DSL automatically compensates for the acoustical difference
between the couplers.
NAL recommends performing the RECD measurement using the coupler that
will be later used for performing coupler measurements. That is, when fitting a
BTE aid, use an HA-2 coupler for the RECD. When fitting a canal aid such as an
ITE, ITC, or CIC, use an HA-1 coupler. Unlike DSL, NAL doesn’t compensate for
the difference between the HA-1 and HA-2 couplers.
FP40 and 6500-CX Analyzer
The coupler measurement part of the RECD is taken with a 50 Ohm insert earphone plugged into the external speaker jack of the FP40 or 6500 hearing aid
analyzer. Once this measurement has been taken, it will automatically be used
for all future RECD measurements, even those taken with different clients.
1. Connect the insert earphone to the appropriate coupler. There are several
different possible methods. Use the method most appropriate for your fitting.
• BTE without custom mold available and ITE/Canal per DSL specs:
Connect the insert earphone directly to the ear level adapter on an
HA-2 coupler.
• BTE with custom mold: Connect the insert earphone to the patient’s
custom ear mold, and use putty to connect the ear mold to the HA-1
coupler.
• ITE/Canal per NAL specs: Connect the insert earphone to an HA-1
coupler using a foam ear tip and Fun Tak.
2. Thread a probe tube through the probe calibration adapter. The tip of the
probe tube should extend no more than three millimeters past the nonridged end of the adapter. Fix the probe tube in place at its entry point,
with a bit of Fun-Tak. See Figure 6.2.4.1A.
3. Push the probe calibration adapter into the coupler.
4. Plug the insert earphone into the external speaker jack on the back of the
analyzer.
5. Click Get RECD in the Audiometry window. This will open the RECD
measurement window. See Figure 6.2.4.1B.
6. Select Coupler.
7. Select the source level by using the arrow buttons located to the left of
the Coupler button. The default level of 70 dB SPL is recommended.
8. Click Start Test. The coupler measurement will be performed.

FP35 and 7000 Analyzers
The coupler measurement part of the RECD on the FP35 and 7000 analyzers is
made according to the calibration procedure described in the Operator’s Manual
of the analyzer. WinCHAP merely gathers this data when the real-ear part of the
RECD measurement is performed.
6.2.4.2 To perform the real-ear measurement (all analyzers)
1. Position the earhook on the client’s ear. Attach the probe microphone to
the earhook. The reference microphone is not used in this measurement.
2. Insert probe tube into client’s ear.
3. Insert the client’s custom earmold or a foam eartip into the client’s ear.
Attach the insert earphone. See Figure 6.2.4.2.
4. Open the RECD measurement window by clicking the RECD button in the
Audiometry window.
5. Select Real-Ear in the RECD measurement window.
6. If you are using the 6500-CX or FP40, you can select the source level by
using the arrow buttons located to the left of the Real-Ear button.. The
default level of 70 dB SPL is recommended, but you should select the
level that was used for the coupler measurement. You cannot change the
source level used with the 7000 and FP35 analyzers; those analyzers will
always use 70 dB SPL.
6. Click Start Test. This will start the pure-tone measurement sweep.
7. Click Save Test to store the test results.
8. Click Back to close the RECD window. If you performed the coupler measurement, you will be asked if you wish to save it for future use. If you
click Yes, the measurement will be automatically appear the next time
you perform an RECD, even with another patient.
9. Make sure Measured is selected next to the RECD button.
10. Click Settings to open the Settings window.
• Under the General tab, the Transducer should be set to Insert
Earphone or Insert Custom Mold, depending upon whether you
used a custom mold.
• Under the NAL-NL1 tab, in the Measured RECD selection, choose

6.3 DSL Verification
There are two ways to verify that the hearing aid meets the DSL prescription:
through coupler measurements and through real-ear measurements. In the DSL
window, you can view the coupler and real-ear targets in dB GAIN or dB SPL.
When displaying in dB SPL, you can also view the patient’s thresholds, upper
limits, and the LTASS. Coupler and real-ear measurements can be performed
and compared to the displayed targets. See Figure 6.3.
72 The DSL/NAL-NL1 Module

measurement.
2. Select whether you want to want to display measurement results and targets in dB Gain or dB SPL by filling in the appropriate radio button.
3. Display the target to which you are measuring by selecting it in the target column. If the display is set to SPL, you can also display Thresholds,
Upper Limits, and the LTASS.
4. Select the curve you are going to measure. A checkmark is displayed next
to the current selected measurement curve.
5. Select the Source Type for the curve. Choose between Pure-tone,
Composite, DS ANSI (Digital Speech ANSI), and DS ICRA (Digital Speech
ICRA). The target will automatically adjust to fit the selected source type.
6. Select the SRC (source) of the curve. Choose between 40 and 100 in 5 dB
increments. (95-100 dB SPL is only available for coupler pure-tone measurements.)
7. Click Start to start the measurement. If performing a real-time measurement, click Stop to stop the measurement after it has stabilized.
8. Repeat steps 3-7 to take any other desired measurements. WDRC aids are
usually measured at 50, 65, 80, and 90 dB SPL. Linear aids are generally
only measured at 65 and 90 dB SPL. See Figure 6.3.2.
9. Click Save in the toolbar to save the measurement.

When using WinCHAP to do a research project, it is often useful to be able to
cut and paste the measurement data into a spreadsheet such as Excel. This can
be done in WinCHAP by right clicking on the measurement data. Choose Copy
All to copy all the displayed measurement data to your computer’s clipboard.
You can then go to your spreadsheet project and use CTRL+V to paste the data
there.
If desired, you can also copy a limited amount of data. Click and hold down
the left button of your mouse and use it to select the data you want to copy.
Unfortunately this data is not visibly highlighted. Then use your right mouse
button and select Copy Selection. This will copy only the selected data to the
clipboard.
6.3.3 Testing with Live Speech
The Spectrum Analysis mode, available when your analyzer has the Composite
signal, lets you use the external signal of your choice with your real-ear measurements. You can use sounds from a CD player, the patient’s own voice, or the
voice of a spouse or family member. Using the SPL display in the DSL window,
you can display the reponse to the live speech signal and compare it to the
patient’s threshold values, uncomfortable levels, and the LTASS speech banana.
WinCHAP User’s Manual
The DSL/NAL-NL1 Module 75
To do this, just follow the instructions for testing as described in Section 6.3.2.
In step 5, select the Source Type to Composite. In step 6, set the Src. amplitude
to 0 (Spectrum Mode). Press Start to start the measurement. Now use the live
speech signal as the input source and see how the aid responds to it. Use the
noise reduction setting on the analyzer to control how much long-term averaging the analyzer uses when displaying the measurements. When noise reduction
is set to OFF on the analyzer, the display will update very quickly in response to
all the changes in speech. When the noise reduction is set to 16X, the response
curve will update very gradually, showing the aid’s long-term response to the
speech signal. See your analyzer’s Operator’s Manual for details on setting the
noise reduction setting.
6.3.4 Adding the LTASS
The LTASS is a set of three curves based on the long-term, average speech
spectrum. The middle curve is the average, the upper curve is the average plus
12 dB and the lower is the average minus 18 dB. The LTASS curves show the
boundaries of average speech, and can be used as a counseling tool to show a
client how their hearing range relates to average speech sounds. It can be displayed in the DSL window in an SPL display.
6.3.5 Matching measurements with targets
DSL targets are dependent upon signal type and signal level. When adjustments
are made to the signal, the DSL target makes corresponding adjustments.
Each measurement is tied to a particular target; it is important to compare
appropriate targets to each measurement. Only measurements tied to the selected targets will be displayed. That is, if you have taken a measurement at 65 dB
SPL, and then you change the target to 70 dB SPL, the 65 dB measurement will
be removed from the window but not deleted. You can redisplay the 65 dB measurement by changing the target back to 65 dB.
6.3.6 Understanding Speech Weighting
The DSL method was designed around the LTASS speech weighting. However,
FONIX equipment normally uses the ANSI speech weighting, which rolls off the
high frequencies more gradually. When working in dB Gain, the speech weighting differences have little effect because the speech-weighted input signal is
subtracted out to arrive at the gain values. However, when viewing targets and
measurements in dB SPL, the speech weighting is not subtracted out and has a
large impact on the displayed target.
In order for the FONIX measurements to be directly compared to the DSL targets, WinCHAP has altered the DSL targets to incorporate the FONIX speech
weighting. If you would like to view the targets in their non-altered state,
change the Signal Filter selection in the Settings window under the DSL tab.
You will not be able to take a measurement when this speech weighting is
selected.
76 The DSL/NAL-NL1 Module
WinCHAP User’s Manual
6.3.7 Measuring with Pure-tones
The FONIX FP35, 7000, and FP40 analyzers are equipped with several different types of pure-tone measurements. The “Normal” pure-tone sweep performs
a standard sweep once and automatically stops. The “Fast” sweep measures 16
different frequencies repeatedly until the user stops the test. The “Short” sweep
measures 10 different frequencies once and automatically stops.
WinCHAP automatically specifies the Short signal when performing real-ear
measurements at 90 dB SPL. This means that only one quick sweep will be run
before the test automatically terminates.
You can choose whether you want to use a Normal or a Fast sweep when performing pure-tone measurements below 90 dB SPL by changing the PT Signal
Mode in the Settings window.
Notes:
• The 6500-CX does not have the Fast or Short selections available. Real-ear
pure-tone measurements are performed using only frequencies specified by
NAL and DSL. Coupler measurements are performed with a Normal pure-tone
sweep.
• The FP40 is not very responsive to computer commands during a Fast sweep
when the reference microphone is on. During those conditions, WinCHAP
will only perform only one sweep before terminating the test.
6.4 NAL-NL1 Verification
The NAL-NL1 window is used to fit a hearing aid to the NAL-NL1 fitting formula. You can choose to perform the fitting with insertion gain or gain targets;
any measurement taken in one scaling is automatically converted for use with
the other scaling. The SSPL90 selection is used for testing output at loud levels.
See Figure 6.4.

6.5 Info
The Info window (Figure 6.5) is used to identify the Operator, Analyzer, and
Audiometer used to perform the hearing aid fitting. It also contains the DSL
prescriptions for the amplification that a hearing aid should produce in order to
be a good fit for your client. These values can be compared to the hearing aid’s
published manufacturer specifications.
The coupler values displayed in this window are:
• SSPL: Target maximum output SPL.
• Full-on Gain: A reserve gain ranging from 1 dB to 20 dB (in 1 dB steps) is
used to calculate this target value.
• User Gain: For linear aids, the user gain is tied to the speech spectrum
selected in the DSL tab of the Settings window. It is the output of that speech
spectrum minus its input. For WDRC aids, the user gain is tied to the input
level selected on the Info window. It is the coupler target output at that level
minus its input.

Hearing Aid Measurements
7.1 Introduction
WinCHAP can gather data from nearly all of the tests available on the FONIX
FP40, 6500-CX, 7000, and FP35 hearing aid analyzers.
The following tests and test sequences are available:
• Response curves & Real Ear
• ANSI S3.22-1987
• ANSI S3.42-1992
• ANSI S3.22-1996
• ACIC test sequence (based on ANSI ’87 using CIC coupler and correction
factors)
• IEC
• JIS
Most hearing aid analyzers are not equipped to run all of these measurement
curves; we included all of them to make WinCHAP more universally friendly.
You will, however, only be able to run those automated test sequences supported by your analyzer. If you try to run an automated test sequence that your
analyzer doesn’t support, WinCHAP will give you an error message.
WinCHAP cannot change such variables as source type, aid type, or automated
test sequence setting, so you have to set your analyzer up the way you want
your aid to be tested. WinCHAP will, however, determine those settings from
the analyzer.
The different hearing aid tests that WinCHAP supports can be grouped into two
categories, individual curve tests (Response Curves and Real-Ear) and automated test-sequences (ANSI ’87, ANSI ’96, ANSI ’92, ACIC, JIS, and IEC).
7.2 General Test Information
Every test window in WinCHAP share some similarities and common interfaces.
The functions listed in this section apply to all measurement windows. For
more information on the Response Curves window, see Section 7.3. For more
information the Real-Ear window, see Section 7.4. For more information on any
of the automated test sequence windows, such as ANSI 96, ANSI 87, and IEC,
see Section 7.5.
88 Hearing Aid Measurements
WinCHAP User’s Manual
Each test window has the following features:
• You can check the connection of your analyzer.
• The main window of the display contains graphical representations of the
test results.
• There is a button or tab containing the numerical data of the test results.
• There is a button or tab containing all of the test parameters.
• There are basic analyzer controls that can be performed remotely from
within WinCHAP.
7.2.1 Creating & Opening Tests
All hearing aid tests are attached to a particular hearing aid. These are the steps
you must take to save a hearing aid test in WinCHAP:
1. Create the hearing aid record in the Office Manager or in the Quick Entry
Hearing Aid window. See Sections 3.2.2.1, 3.3.2.1, and 3.3.2.2.
2. Open the hearing aid record in the Test Menu. See Section 4.1.3.
3. Create a new hearing aid test and choose the type of test you would like
to take. See Section 4.2.2.
4. Get the test from the analyzer. See Section 7.3 for information on using
the Response Curves window, Section 7.4 for information on using the
Real-Ear window, and Section 7.5 for information on using the automated
test sequence windows such as ANSI 87, ANSI 96, and IEC.
5. Save the test by clicking Save in the toolbar of the measurement window.
6. Close the window by clicking Back.
7. The new test will be listed under the hearing aid in the Test Menu. You
can open it again by double-clicking it.
7.2.2 Checking the analyzer’s connection
Before you can get any measurement curves from your FONIX analyzer, your
computer must be connected to your hearing aid analyzer. See Section 1.3 and
Section 2.2.2 for instructions on setting up the connection.
Use the Check button in the toolbar of the measurement window to check your
analyzer’s connection. If you are unable to establish a connection, try clicking the Check button again, making sure the analyzer is powered up and that
the connections between the analyzer and the computer are solid. You can also
check your COM port configuration.

7.4.1 Using the Connect button
The Connect button in the toolbar of the Real-Ear window creates a real-time
connection between your computer and your analyzer. The established connection depends on the type of analyzer.
6500-CX
The 6500-CX must be in Auto mode in the Insertion Gain screen and running
an aided measurement. At this time, the 6500-CX cannot establish a real-time
connection in the SPL Testing screen, or while the analyzer is in manual mode
in the Insertion Gain screen.
7000, FP40 & FP35
When the FP40 and FP35 analyzers are in their Insertion Gain screens, the
CONNECT button will establish a real-time connection with the insertion gain
curve. When they are in their SPL test screens, the CONNECT button will establish a real-time connection with the current REAR curve.
General instructions
1. Set up the analyzer and hearing aid for real-ear testing.
2. Start the real-time measurement on your analyzer using a FAST pure-tone
sweep, composite signal, or digital speech signal.
3. Click Connect in the Real Ear Test window to establish a real-time connection. To speed up the connection, the grid lines on the WinCHAP display will temporarily disappear.
4. When satisfied, click Disconnect to end the connection.
5. Click Save to save the measurement.
7.4.2 Getting curves from your analyzer
If you have taken real-ear measurements with your FONIX analyzer, you can get
those measurements using the Get Curves button in the Real-Ear toolbar. The
curves that are grabbed from the analyzer depend on the analyzer model, software version, and the mode.

WinCHAP User’s Manual
7.4.3 Sending a target to your analyzer
Instead of manually generating a target on your analyzer, you can send the target to your analyzer from WinCHAP.
See Section 5.5.1 for instructions on generating an insertion gain target from
WinCHAP and sending it to the analyzer. See Section 5.5.2 for instructions on
sending an audiogram to the analyzer.
7.4.4 Sending curves to your analyzer
You can send any curve displayed in the Real-Ear window to your analyzer
using the Send Curves button.
1. Choose the curves you want to send to your analyzer by having them displayed on the window. You can send up to four curves. If you have more
than four curves displayed, only the first four will be sent.
2. Click Send Curves. This will open a new window.
3. Select Probe.
4. Select the desired ear.
5. Click Go to send the curves. A window will open, confirming that the
curves have been sent.
6. Click Back to close the Send Curves window.
7.4.5 Adding Curves & Deleting Curves
The Real-Ear window has many similarities to the Response Curves window.
Like the Response Curves window, you can add saved curves to the graph, you
can delete curves from the graph, and you can create custom labels for the displayed curves.
To do these things, see the explanations in Section 7.3.5, Section 7.3.6, and
Section 7.3.7, respectively.
7.5 Automated Test Sequences
There are six different automated test sequences that you can store in WinCHAP
after you’ve run them on your analyzer. Figure 7.5 shows an example of the
ANSI 87 automated test sequence screen.
• The ANSI 87 sequence runs a complete test of the hearing aid in accordance with the ANSI S3.22-1987 requirements.
• The ANSI 92 is an automated test sequence the uses a noise signal to give
you a family of curves and is according to ANSI S3.42-1992.
• The ANSI 96 sequence is a revision of the ANSI 87 sequence and is
designed to more thoroughly test AGC aids. Telecoil testing has also been
extensively changed.
WinCHAP User’s Manual
Hearing Aid Measurements 103
• The ACIC sequence runs the same tests as the ANSI 87 sequence using
the FONIX CIC coupler and CIC corrections. This test is not, therefore, an
ANSI S3.22 sequence.
• The IEC sequence is an automated test used by the international community.
• The JIS sequence is an automated test used primarily in Japan.
Figure 7.5—The ANSI 87 automated test sequence window
7.5.1 Getting a test sequence
The most straight forward way to save the automated test sequence results into
the database is to use the Get Test button:
1. Set the analyzer up for normal coupler testing.
2. Run the automated test sequence on your analyzer as you normally
would.
3. Click Get Test in the automated test sequence window in WinCHAP. The
will cause WinCHAP to grab all test data currently displayed on your analyzer.
4. Click Save in the toolbar to save the results.
104 Hearing Aid Measurements
WinCHAP User’s Manual
7.5.2 Starting a test sequence
If your analyzer is already set up for testing, then you can remotely start the
automated test sequence from WinCHAP by clicking Start Test:
1. Set the analyzer up for normal coupler testing.
2. Click Start Test in the automated test sequence in WinCHAP. This will
remotely start the automated test sequence on your analyzer.
3. If the analyzer pauses midway through the test to allow for adjustment of
the hearing aid to reference test gain (or to put the aid in telecoil mode),
a window will pop up on WinCHAP, telling you what to do. Adjust the
hearing aid accordingly.
4. Click OK in the test window when you have done the adjustment.
WinCHAP will tell the analyzer to resume testing. When the test sequence
is done, WinCHAP will display the results.
5. Click Save in the toolbar to save the results.

WinCHAP NOAH® 3 Module
8.1 Introduction
The FONIX WinCHAP NOAH module is a program that runs inside NOAH 3
and allows you to import and export data between NOAH and WinCHAP. More
specifically, you can use it to:
• Export client information from NOAH 3 to WinCHAP
• Import and export the client’s audiogram to and from NOAH 3 and
WinCHAP
This lets you grab a NOAH audiogram and insert it into WinCHAP. From
WinCHAP, you can either create one of the linear targets and send it over to
your FONIX hearing aid analyzer (see Section 5.5.1), or you can use the DSL/
NAL test to perform DSL or NAL-NL1 fittings (see Chapter 7).
All real-ear and coupler measurements are saved in WinCHAP and not in
NOAH 3. If you want to work exclusively in NOAH 3 and not use the WinCHAP
database, see our other program, the FONIX NOAH Module.A free demo of this
product is available on our website: http://www.frye.com.
There is also a separate NOAH 3 import utility in WinCHAP that allows you to
import the entire NOAH 3 database using the NOAH 3 XML data export function. This is described in Section 8.6.
8.2 Installation & Setup
This section describes how to install the WinCHAP NOAH Module inside
NOAH and open it, once it has been installed.
8.2.1 Installing the WinCHAP NOAH Module
There are two ways to install the WinCHAP NOAH Module. The easiest way is
to install it from WinCHAP. You can also install it from NOAH 3.
8.2.1.1 To install the NOAH Module from WinCHAP
This method is the easiest (and the preferred) way to install the NOAH 3
Module.
1. Make sure you have properly installed WinCHAP. See Chapter 1. NOAH 3
should also be installed.
2. Open WinCHAP.
3. Open the Tools menu and select NOAH 3 Tools. This will open the NOAH
3 Tools window. See Figure 8.2.1.1.
4. Click Install NOAH 3 Module to install the WinCHAP NOAH Module. A
window will pop up, confirming your success.

the WinCHAP executable and database files are located. If for some reason this
doesn’t work, you can set these locations manually.
1. Open the Frye Tools menu.
2. Point at Settings and select Set WinCHAP Database
WinCHAP User’s Manual
The NOAH 3 Module 107
3. Using the file manager, select the location of the WinCHAP database. The
default location is:
C:\Program Files\Frye Electronics\WinCHAP\Winchap0.mdb.
However, the location of your WinCHAP database file may be different.
When in doubt, open WinCHAP and look at the bottom of the WinCHAP
window; the pathname and the file name of the database file will be displayed.
You may have to repeat this process to set the WinCHAP executable file.
This is usually in the location: C:\Program Files\Frye Electronics\WinCHAP\
WinCHAP32.exe.
8.3 NOAH Audiograms
The NOAH Audiogram Section contains a listing of all audiograms saved in
NOAH 3 for the current client. See Figure 8.3.
In order to use an audiogram saved in NOAH 3 to create a target in WinCHAP
and send that target to your FONIX analyzer, you must first export the NOAH
audiogram to WinCHAP.
To export NOAH audiogram to WinCHAP
1. If needed, click on the NOAH Audiogram tab to enter the NOAH
Audiogram Section and display the window shown in Figure 8.3.
2. Select the desired NOAH session in the top box.
3. Select the desired audiogram in the bottom box.
4. Click Export Audiogram to WinCHAP.
Note: If the current client information does not exist in WinCHAP, it will automatically be exported to WinCHAP with the audiogram.
If you don’t see the NOAH session or audiogram you want to export, try clicking Refresh Session List. This will update the NOAH listing of sessions and
audiograms.
