GENERAL SETUP
This application generates audible tones to make specific adjustments to AMP hearing aids. For best
programming results, headphones should be used to play the tones in the patient’s ears. The builtin speaker system on the computer may be used with this application; however, the tones must be loud
enough to be detected by the AMP hearing aids. If there are no headphones attached to your computer
then simply position the speaker output close to the patient’s ear when an adjustment is made.
APPLICATION ICON OVERVIEW
ICON
DESCRIPTION
Speakers Icon Choose this icon if you are using
speakers to present the tones.
Headphones Icon Choose this icon if you are using
headphones to present the tones.
Ear Selection Icon Controls whether the tone sequences
will be played monaurally or binaurally. This is available
for headphones only. The three options are: right
(monaural), left (monaural) or binaural (delivered to both
ears simultaneously).
Volume Control Increases or decreases the volume of
the tones.
Fitting Preset Icons Icons represent the four fitting
presets. There are three based on audiometric
configurations and one that is full-on gain.
(Please see Fitting Preset Guide below)
Adjustment Icon Decreases the parameter setting.
These values are relative to the selected preset and each
step size is 2dB.
Adjustment Icon Increases the parameter setting. These
values are relative to the selected preset and each step
size is 2dB.

TONE SEQUENCES
There are two methods where tones are generated through the fitting process: 1) tonal sequences
emitted from the computer representing the adjustment commands and 2) tones emitted from the AMP
hearing aids in response to the changes to the settings.
ADJUSTMENT COMMANDS
This application uses Dual Tone Multi-frequency (DTMF) signals as the adjustment commands. Each
adjustment command has a unique, tonal sequence consisting of three DTMF signals, representing the
adjustment commands. The audio level of the adjustment commands is controlled by the audio level of
the computer.
INDICATORS
The AMP hearing aid will play audible tones that provide confirmation that an adjustment command
has been applied successfully. Tones will play to confirm the chosen preset (one tone for Preset 1, two
tones for Preset 2, three tones for Preset 3 and four tones for Full-On Gain). Immediately following
the adjustment command tonal sequence, the AMP hearing aid will respond with one of two tonal
sequences: 1) a warble tone sequence confirming the change or 2) a series of high and low tones
representing that no further adjustments can be made for that particular setting.
The levels of the indicators are set, with presets 1 & 2 using the same level and 3 & 4 being 10 dB
louder. The indicators are also adaptive in nature, which means that the level will be adjusted louder in
volume if there is measureable background noise in the environment during the fitting process. If the
patient does not hear an audible tone generated in the device after an adjustment has been made,
repeat the adjustment. If using a speaker, move the speaker of the device closer to the AMP hearing aid
and repeat the adjustment.
