Affi nity HIT440 Module

- Effi cient Hearing Aid Testing

Hearing instrument testing

With HIT440 Hearing Instrument Testing module the

Affi nity takes hearing aid evaluation to a whole new level in its ease of use and fl exibility.

Directional microphones

Directional hearing aid microphones can be tested in the integral test box and all tests can be directly compared to previous measurements made on the same hearing aid.

All client data can be saved directly to NOAH or

Interacoustics’ own IABaseII database during the hearing aid fi tting. You can also choose not to use a database for quick and easy hearing aid evaluations. While preloaded standard ANSI and IEC protocols including coil measurements can get you up and running quickly you can also create your own protocols or import specialized tests such as those that are developed specifi cally by hearing aid manufacturers.

Easy reporting

You can print a customized report at the end of the session or gain immediate access to the data from previous test sessions. You no longer have to print the data and paste it in a fi le – now you can save it and verify hearing aid functionality over time, even compare tests right on your PC screen.

Other benefi ts of the HIT440 module:

• Easy upgrade with new tests

• Tests digital hearing aids

• Report page for session notes

Fit for the future

The HIT440 module is designed to test traditional hearing aids as well as digital hearing aids. Special stimuli and test procedures are available and include

ICRA noise and real speech. Most importantly is the open architecture of the Affi nity software platform. As new technology is developed future hearing aids will require special stimuli that are not known today. While you may have had to buy a new hearing aid testing device to keep up with hearing aid technology in the past, the Affi nity has the ability to simply load new test stimuli and procedures on its platform.
