Hearing Aid Fitting
A complete solution
The Affinity2.0 is a user friendly Hearing Aid Analyzer that interfaces with a full range of integrated audiologic software modules on your laptop
or desktop PC. This combination of hardware and
software make the Affinity2.0 the perfect instrument for hearing assessment, hearing aid fitting
and patient satisfaction.
Modules – your security for the future
Audiometry (basic & advanced)
Hearing Aid Testing
Real Ear Measurements including
Visible Speech Mapping
As new hearing aid technologies evolve – so
will the Affinity2.0. The Affinity2.0 modules will
be upgraded as new stimuli or other advanced
techniques become available. All associated patient records are stored in NOAH or through our
own database program called OtoAccess™. Both
programs are networkable.
The Affinity2.0 is
available with audiometry,
real ear measurement,
visible speech mapping
and hearing aid testing
software modules.
A complete package
The Affinity2.0 has the complete package with
modern applications for dispensing and clinical
evaluations. From beginning to end, the Affinity
provides high quality components with software
features that guide you through the process of
evaluation, remediation/counseling and professional report generation. Streamlining procedures
is made possible with special exporting and
importing functions that enable businesses with
multiple office locations to standardize protocols
and reports. Data management can be shared
between offices and integrated into Electronic
Medical Records.
Printouts and reports – your own designs
Printed reports are user designed through a print
wizard and include a complete set of default
reports. Data can be imported into the system,
a feature used by dispensing chains to distribute
standard tests to their stores and by dispensers
to download specifications from a manufacturer.
Output from Affinity2.0 is in PDF or XML format
depending on the purpose.
Sales and Counseling
A Visible Speech Mapping module is available
with the Affinity2.0 to assist you in educating the
client and family members on the complexities
of hearing aid amplification and the benefits
they will receive. Client decisions on cost/benefit may hinge on their comfort level during the
educational process and Visible Speech Mapping
technology will have a positive influence on their
total hearing aid selection experience.
Personal settings and protocols
The Affinity2.0 permits personalized test configurations to match your clinical needs. The Affinity2.0
includes a set of tests that may be modified to
quickly get you up and running to your own standards and stored for future use.
These user defined protocols are saved under
a unique name for easy recall via a drop down
menu. This enables multiple users to make test
selections that are suitable for their own applications. Larger clinics or dispensing facilities will
find this feature useful as these protocols can be
downloaded and transferred to these sites over
the internet.
Tracking changes
Adding your observations to test results is often
valuable when clients make repeat visits or have
special needs. In addition, the integrated database allows results from different dates to be
displayed together. This saves time when
troubleshooting a hearing aid and is important
when monitoring the progression of hearing loss
in a client. Comparisons can be both onscreen
and printed in reports.

Real Ear Measurement
Real-Ear Measurement is the only objective analysis
available to measure the hearing aid output while
the patient is wearing it. The REM440 software is a
reliable verification tool that includes a wide range
of functions for verifying hearing aids, including the
increasingly popular open fit instruments. Now an
additional patient centered counselling and verification tool (Visible Speech Mapping) is available.
ries of client (e.g. adults and or children) or different clinicians using the Affinity2.0 can design their
own protocols. Or you can use specific aid types.
This will often save you significant time and is more
convenient. User protocols are stored on a drop
down menu and run by single click selection.
Open fit capability
The Calibrate for Open Fit function (substitution
method) handles the new trend of open fittings
seen in products like Oticon Dual, Phonak Micro
Savia and Widex Passion. It provides a wide range
of settings and stimuli for testing non-linear
hearing instruments.
RECD and normative data
Thanks to the benefits of universal neonatal hearing
screening (UNHS) an increasing number of babies
with hearing loss are identified within 6 months of
age. As a result more infants and small children are
referred for hearing aid fitting in which Real-Ear to
Coupler Difference (RECD) is an essential measure.
Specially designed components enable a rapid testing of small children whose attention span is very
short. In cases where measurement of REUR and
RECD is not practical, REM440 provides age related
normative data to approximate these values.
Testing advanced features
Hearing aid technology has dramatically improved
over the past decade. Advanced features and algorithms are common in modern digital hearing aids.
The REM440 allows for verifying some of these
advanced features such as Directionality and Noise
Concurrent operation
The REM440 can be open at the same time as
other fitting applications to enable smooth adjustment and verification of the hearing aid.

Visible Speech Mapping
- Verification, counseling and sales in one!
The Visible Speech Mapping module is designed
to assist clinicians in the important process of fitting and counseling. Incorporated in a verification
screen the system addresses the task of explaining
technical issues to non technical users.
Visible Speech Mapping – a verification tool
Visible Speech Mapping merges real-ear verification and counseling into one screen. You can
match the amplification to target (e.g. DSL mi/o
v5, NAL-NL1) on an aided display and at the same
time show the hearing aid benefit by comparing to an unaided display. The comprehensive
layout showing dynamic range, normal hearing
thresholds, and sound examples assists you in
the process of communicating the measurement
results and making recommendations.
Visible Speech Mapping – a counseling and
sales tool
Realistic expectations are the major psychological
factor in use of the hearing aid. Visible Speech
Mapping is a practical tool to that end. Explain
compression, binaural benefits, and other
advanced features in a simple way - also to
relatives who are often a motivating factor when
people seek hearing assistance. Demonstrate
and explain the difference between two different hearing aids in order to help them make their
final decision when purchasing instruments.
Wave player and external sounds
Stimuli in Affinity2.0 are not restricted to standard
tones and speech. You can add files in WAV format containing any type of noise. You can even
record a relatives voice and play it back through
the WAV player to find out which of two settings
work best. External sounds may be added by using a CD player.
Also for children
Visible Speech Mapping can be used in the adult
as well as the pediatric hearing aid fitting. Based
on individual or predicted RECD values Visible
Speech Mapping can be performed in the 2 cc
coupler. This is particularly helpful when fitting
hearing aids to children. Parents of children with
hearing loss are entering a whole new world with
a terminology all of its own. By helping parents to
absorb and understand what they need to know,
Visible Speech Mapping makes counseling and
verification a positive experience.

Audiometry software
The AC440 software turns the Affinity2.0 into one
of the most powerful diagnostic audiometers
available today. Above and beyond the standard
air, bone and speech capabilities, there are a wide
variety of test applications that make it ideal for
the high end clinical environment or for any active
dispensing practice. Multiple methods of using
the software allow previous experiences with
stand alone devices to transfer easily. Historical
data retrieval will display overlapping audiograms
for diagnostic and educational purposes and even
transfers immediately into the REM440 fitting
Report page
Each test session contains a report page which
functions as a holding place for comments. This
ensures that vital tester observations are not lost
and can also function as a summary page for test
results. The report page is saved with the test
results and made available whenever the session
is recalled.
Full test battery
The AC440 has a basic set of test for traditional
audiometry but also includes a battery of tests
suitable for CAPD, differential diagnosis, tinnitus,
hearing loss and hearing aid simulations.
Sales and counseling
The AC440 can be supplemented with modules
for Hearing Loss Simulation (HLS440) or Master Hearing Aid (MHA440). These tools engage
clients and relatives in the fitting process. This is
especially important in establishing the trust and
confidence of first-time users.
Historical sessions
Any historical audiogram can be retrieved for display while you are performing a test, or after you
have completed the examination. It is an invaluable tool when assessing changes over time with
your clients and aids in the counseling process.
User protocols and customization
User protocols are great time savers. They are collections of settings for a particular test procedure
or clinician. They enable you to save your preferences or standard procedures on a drop down
menu from where you can load or run them with
a single click. There is no limit to the number of
protocols you can save.
Dedicated keyboard
The AC440 has an optional dedicated audiometric keyboard to aid in the transition from stand
alone equipment to PC based. Function keys may
be customized to eliminate the cycle of menu
driven selections and speed up your test time.
Data extraction and output
The modern era of electronic medical records
requires methods of data extraction for condensing patient records and sharing information across
clinics. The Affinity2.0 is designed to streamline this
process, thereby improving economy, efficiency
and speed of data management. Data may be
extracted in PDF and XML formats for printouts
and email attachments.
High Frequency (HF440)
The high frequency option on the AC440 software module permits an extended frequency
range out to 20KHz which is typically used
for ototoxic monitoring. When used with the
Multiple Frequency selection it becomes and
even more powerful tool for discreet analysis of
Masking Level Difference
The MLD test is used as part of the CAPD test
battery. Low frequency stimuli in combination
with NB noise (binaurally) and acoustical phase
differences will produce threshold shifts and may
help identify persons with auditory binaural integration problems.
Speech tests from the hard drive
This feature saves time by eliminating the need
for an external CD player for the majority of your
speech tests. Choices for scoring methods allow
you to customize the word presentations and
view the chosen word lists.
