This bulletin describes how to use the Program manager in REAL fittings using Compass V4.6. The descriptions refer to the Program manager in the Fine
tuning window. You access the Program manager from the Toptool bar. Please
refer to Compass in order to see the details of the screen. Remember that Compass offers several help functions to explain the different options in the program: Tooltips, Solution guide, Using this window panels and the help manual.
The REAL hearing aid is, by default, a one program hearing aid, with a Master program designed to
provide the best possible overall performance in all environments with all adaptive features working
together to optimise audibility, intelligibility and comfort. However, some hearing aid users encounter environments in which they may wish the hearing aid to operate with a different focus. For this
purpose, REAL features a range of additional listening programs that can be selected initially during
the fitting procedure, or later on during follow-up. In the Fine tuning window, the Program Manager
is accessible from the Toptool bar. The Program manager allows you to select, copy and delete listening programs, as well as to change the order of the programs. The Program manager offers a selection
of different program templates that may serve as inspiration in the hearing aid fitting process.
The Program manager allows you to select, add, copy, delete and change the order of the programs in the hearing
aid

Using the Program manager
To add a program, select the desired program name in the program list and select the add arrow button or double click on the selected program. Whenever you point to or select a program, an illustration or a short explanation of it is displayed on the screen. Click the button in the lower right hand
corner to shift between illustration and explanation.
The Program manager allows you to select more than one program of the same type either by selecting two identical programs from the program list or by using the copy button in the program item
you want to copy. Selecting identical programs from the program list gives you programs with default
settings, while a copy will include any fine tuning performed in the original program. You can change
the program order by pressing the arrow buttons in the program item in the Program manager.
Press the delete (trash can) button for a program item you want to delete. Note that the original
Master program can never be deleted. Before you delete a program, it can often be useful to save your
fitting in the NOAH database using the save button in the Toolbar. This will allow you to re-establish
the deleted program including any fine tuning you may have performed.
In binaural fittings you will typically have identical programs in the two hearing aids. It is possible to
have a different number and different types of programs in the two hearing aids. Press the appropriate adjustment icon for the left or right hearing aid, which allows you to select programs individually
for the two hearing aids. Be aware, though, that such a choice requires extra careful counselling of the
user. We strongly recommend that the number of listening programs in binaural fittings is identical
to avoid any confusion. You should also be aware that two hearing aids cannot be operated with the
same remote control unless the number of programs in the hearing aids is identical.
Program types
The Program manager offers a selection of listening programs. A maximum of three programs can be
selected in the basic Program manager. Please be aware that CIC hearing aids only have one program
– the Master program. Note that the number and type of listening programs should always be selected based on an analysis of your client’s auditory needs as well as his/her ability to understand and
manipulate the program button or remote control.
Depending on the Direct Audio Input system you use, the M-DAI and DAI programs may be placed
at program location 1 and 2. You must use the DAI Manager to set up the DAI system correctly for
the equipment you use.
Please be aware that telecoil programs are not available for CIC hearing aids, m models and for ITE
instruments without DAI programs and telecoil.

Master
Provides the best possible overall performance in all environments. All adaptive features work together to optimise audibility, intelligibility and comfort.
The default settings in this template are:
•
•
•
•
Gain/compression characteristic optimised for audibility, intelligibility and comfort
Microphone mode is set to Locator (Locator omni for CIC)
Speech and noise mode is set to Classic noise reduction
Feedback cancelling mode is set to On
Music
Focuses on optimum reproduction of music, whether it is performed live or played from stereo or surround systems. The program emphasises low frequencies. Not available for the CIC aids.
The default settings in this template are:
•
•
•
•
Gain/compression characteristic optimised for music (low frequency emphasis)
Microphone mode is set to Locator omni
Speech and noise mode is set to Off
Feedback cancelling mode is set to Off
TV
Focuses on optimum reproduction of sound from television sets. TV and radio signals are very different from normal acoustic signals produced in the environment, as they have already been processed
(compressed). The TV program takes this into account in its compression characteristic. The program
attenuates low frequencies and emphasises high frequencies. Not available for the CIC aids.
The default settings in this template are:
•
•
•
•
Gain/compression characteristic optimised for TV sound
Microphone mode is set to Locator (Locator omni for CIC)
Speech and noise mode is set to Classic noise reduction
Feedback cancelling mode is set to On
Acclimatisation
This template is designed for the first-time user who needs an alternative setting during the acclimatisation period. It is sometimes an advantage to reduce gain a little, so that the new sound picture does
not cause any discomfort. The gain can then be gradually increased over four acclimatisation stages.
Not available for the CIC aids.
The default settings in this template are:
• Gain/compression characteristic optimised for first-time users (reduced gain for all input levels
(especially in the high frequencies) compared to the Master program)
• Microphone mode is set to Locator (Locator omni for CIC)
• Speech and noise mode is set to Classic noise reduction
• Feedback cancelling mode is set to On
5
MT
An acoustic program combined with the input from the telecoil. Not available for the m model, CIC
and ITE without telecoil.
The default settings in this template are:
•
•
•
•
Gain/compression characteristic set as the Master program
Microphone mode is set to Locator omni
Speech and noise mode is set to Classic noise reduction
Feedback cancelling mode is set to On
T
Focuses on the input from the telecoil. Not available for the m model, CIC aids and ITE aids without
telecoil.
The default settings in this template are:
• Gain/compression characteristic set as in the Master program
• Speech and noise mode is set to Classic noise reduction
How to demonstrate the different listening programs
Note that the purpose of the Program manager is to select a program combination - not to demonstrate the programs. When the Program manager is open, the Master program will be active in the
hearing aid. Once you have closed the Program manager, you can shift between the selected programs
using the Program starter, which allows the user to listen to the differences in sound processing.
