Trumpet is an advanced and easy-to-use Real Ear Measurement system, capable of performing quick and accurate in-situ measures thanks to its small lightweight probes and its built-in amplified speaker. Trumpet also incorporates a diagnostic audiometer for carrying out air, bone and speech audiometric exams.
Controlled directly from your computer, Trumpet offers a complete but simple and intuitive software interface, making it a compact and portable system with no compromises.


As a fitting system, Trumpet is capable of measuring all the standard gain/response values: unaided (REUG/R), aided (REAG/R), insertion (REIG) and occluded (REOG/R).
Sequences of measurements can be set and run with just a few clicks, making the daily workflow that much quicker and easier.


Trumpet offers the most recent target protocols, like NAL-NL1, NAL-NL2 and DSL v5, to assist acousticians in the setting of hearing aid parameters, so that fittings will be well accepted, and patients less likely to return dissatisfied.


This most recent and effective counseling tool is naturally available on Trumpet. Live mode for speech mapping allows you to demonstrate the benefit of wearing the hearing aid straight away, by simply talking to the patient, just as any family member might do.


Input-output view mode, higher frequency resolution and complete user customizable work procedure are just some of the additional features available in Advanced mode.


With Trumpet, there is also the option of a kit with built-in speaker, 2cc coupler and insert earphones, which will allow RECD measures to be taken from non-collaborative patients without the need for a hearing instrument test-box.


In audiometer mode, Trumpet can perform air, bone, free field and speech audiometry exams, Hughson-Westlake automated audiometry, QuickSIN®, and includes a 2 channel Master Hearing Aid.


Connect Trumpet to the USB port of your Windows® computer and you are ready to go: no driver and no additional cable required.
You can control Trumpet through the amazingly user-friendly Maestro software interface and, if need be, transfer the data directly to Noah.
