Hearing Loss Simulator
The Hearing Loss Simulator demonstrates the effect of the client’s hearing loss for the
significant third party. The program attenuates an input signal to simulate the audiogram.
The third party listens to the free field speakers. The third party can hear how their own voice
is distorted by the hearing loss when the
Record
input option is used.
The Hearing Loss Simulator requires the client’s Audiogram data. This data can be manually
entered in the Audio screen of this or any other task.
How to perform the Hearing Loss Simulator task
1.
Select the
Hearing Loss
Simulator
tab on the
toolbar.
2.
Enter the Audiogram values
manually if the data is not
automatically imported to
this screen.
3.
Select the input signal type:
Mic, File
or
Record.
Select
the track and the
Play
button on the control panel.
See below for instructions
on how to use the Record
option.
The HLS output is directed
to the free field
loudspeakers.
4.
Select
Normal
to play the input signal as a person with normal hearing would perceive it.
Select
Simulated
to turn on the simulation of the client's hearing loss. Toggle between
these selections as necessary.
5.
The
Reset
option restores the audiogram to the original state. Use this option if you have
modified the audiogram while in the simulate mode but want to undo the changes. The
changes to the Audiogram that are made on the HLS screen are temporary and will not
affect the client's original audiometry record.
6.
A volume control adjustment bar allows modifying the audio for manual adjustment of
the output level of the free field speakers. This allows the practitioner to demonstrate
improvements to hearing loss with amplification or what happens when further hearing
loss occurs.
7.
To stop the playback, select the
Stop
button on the player.
NOTE
: It is recommended you use a variety of tracks from the list to demonstrate the hearing
loss.
