Drum
Drum
Drum is a hearing instrument test box (HIT) capable of an impressive ambient sounds attenuation, and featured with all the standard tests for evaluating performances of air conduction hearing aids. Directly controllable from the Maestro software, Noah compatible and equipped with coupler and all adapters for any type of hearing aids, Drum is the perfect solution for those most demanding users who are not willing to compromise on user friendliness of their instrument.
AUTOMATIC TEST SEQUENCES
Both IEC 60118-7 and ANSI S3.22 standard sequences for Hearing Instrument testing are available on Drum. Automatic protocols with selectable tests, and tooltips for user actions required are specially developed for simplifying the testing procedure.
HIGH ATTENUATION OF AMBIENT NOISE
Size and shape of Drum are 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 is the perfect test box for getting the highest quality test results.
COMPUTER CONTROL
Connect Drum 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.
