Flute (Diagnostic Middle Ear Analyzer)

Flute is a diagnostic middle ear analyzer, capable of performing incredibly fast and reliable automatic sequences of tympanometry and reflex threshold tests, as well as manual reflex and reflex decay tests, ETF test, and high frequency tympanometry.
Great versatility, a user-friendly interface, advanced features and small size make Flute the ideal choice for a wide range of users, from hearing aid dispensers to clinics and hospitals.

Automatic test sequences

Speed up your middle-ear tests with the two available automatic exam sequences combined with special “fast” algorithms, all accurately developed to shorten the time needed for tympanometry and acoustic reflex assessments.

Ultimate hardware technology

Flute features an innovative pump technology for continuous air flow and a finely-designed probe. All combined to fit into an incredibly lightweight (just 2 kg) case.

The probe

Flute features an extremely light, small and sturdy metal probe, which can be very rapidly disassembled and cleaned. The probe is connected to the small Control Box, through which you can select the ear and start the exam.

Noah & Maestro integration

Simply connect Flute to a USB port on your computer (no driver needed), and you can transfer exam results into your Maestro or Noah database. And with the live view feature, you can have a wide view of the examination in progress on the computer display.
