Testing hearing instruments
With AURICAL HIT and the OTOsuite HIT Module you can test the performance of hearing instruments according to both
ANSI and IEC standards. You can also perform coupler-based fitting as described in the AURICAL FreeFit and the Probe
Microphone Measurements User Manual.
Testing a hearing instrument involves the following main tasks:
1.
Calibrating the reference microphone
Otometrics recommends that you calibrate the reference microphone daily or weekly. Set up the interval to suit your pur-
poses. See
