REM System-Audiometer


Trumpet is an advanced and easy-to-use Real Ear Measurement system, capable of performing quick and accurate in-situ measurements thanks to its small lightweight probes and its built-in amplified speaker. It also incorporates a diagnostic audiometer for carrying out air, bone and speech audiometric exams.


Trumpet is a scalable system, available in the following configurations:

  • Trumpet REM
    To fit hearing aids using standard GAIN/RESPONSE measures or
    Speech mapping.
  • Trumpet AUD
    To perform AIR, BONE, Free Field Pure Tone and Speech audiometry exams, Hughson-Westlake automated audiometry, QuickSIN™ (opt.), Master Hearing Aid and Stenger.
  • Trumpet REM & AUD
    To get the most complete solution (audiometry and REM). Optional licenses are available for Trumpet REM and Trumpet AUD to unlock, respectively, audiometry or REM functions.


Trumpet makes use of lightweight probes, available both wired and wireless (opt.), which allow bilateral testing to speed up the exam. The built-in speaker can be used for reproducing signals, selectable from a library, during REM tests, as well as for performing audiometric exams in free-field.


Innovation and technology in just 50 g / 0.11 lb, make wireless probes for Trumpet the lightest available on the market. Trumpet’s wireless probes are designed to improve patient’s comfort and give complete freedom when performing in-situ measurements, thanks to a stable Bluetooth connection and up to 4 hours of uninterrupted use.


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