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.
Record Input Option
This option allows recording and play back of the voice of the third party.
Note: The LSM option appears on the bottom half of the display. This is so the unaided and
aided results can be displayed simultaneously for the patient and significant third party.
