Test results
seem incorrect
If your test results seem to be incorrect, do the following:
1. Open AURICAL HIT and remove the hearing instrument and the coupler microphone.
2. Point the reference microphone towards the area of the coupler microphone socket in
AURICAL HIT.
3. Close the lid.
4. Run the test.
5. Look at the curve at 90 dB SLP. It must be as flat as possible.
6. If it is not, make a Validation Report, recalibrate, and repeat the sequence above.
7. If test results still seem incorrect, replace the relevant microphone and calibrate the new
microphone.
Too much ambi-
ent noise
In order to exclude ambient noise and to comply with the ANSI S3.22 standard, place the system in
a moderately quiet room.
•
If noise enters the test chamber, try moving the device a little, as this can cause big changes in
the noise level of certain frequencies.
•
If noise enters the test chamber via the table or stand, try adding a heavy-duty mounting mat
or replace the table or stand with a more suitable support.
•
If needed, place the PC and any other equipment on a separate table to prevent noise and
vibrations from influencing sensitive tests.
