Inventis Drum fitting HIT (Hearing Instrument Test) box is a hearing instrument test box (HIT). It is capable of impressive ambient sounds attenuation, and featured with all the standard tests for evaluating performances of air conduction hearing aids. Directly controllable through the Maestro software.
Automatic Test Sequences:

Both ANSI S3.22 and EN 60118 standard sequences for Hearing Instrument testing are available on Drum HIT. Automatic protocols with selectable tests, and tooltips for user actions required are specially developed for simplifying the testing procedure.

High Attenuation of Ambient Noise:

Inventis Drum fitting HIT is engineered to maximize the attenuation of ambient noise and minimize the internal sound reflection. Made of wood, featuring an egg-shaped internal chamber and, thanks to the sound-transparent foam at the bottom, offering a floating positioning of the hearing aid exactly in front of the speaker, Drum fitting HIT is the perfect test box for getting the highest quality test results.

Computer Control:

Connect Inventis Drum fitting HIT to the USB port of your Windows® computer, the electrical grid, and you are ready to go: no drivers and no additional cables required. You can control Drum through the amazingly user-friendly Maestro software interface and, if need be, transfer the data directly to Noah.
