Piano is an advanced clinical audiometer featuring a complete battery of tests, including High Frequency, easily managed via the wide touch screen color display.
Advanced features, supreme flexibility and extreme simplicity of use make Piano the ideal choice for clinics and hospitals, as well as for professional practitioners who demand the very best from their instruments.
Piano is available in three configurations to suit different user needs: Basic, Plus and Plus VRA. The three models differ in terms of the number of tests provided.

“Basic” model

Piano Basic provides manual and automated pure tone audiometry and speech audiometry, as well as ABLB, Tone Decay, SISI, Difference Limen Intensity (DLI), Monaural Loudness Balancing (MLB) and Stenger tests and includes a 2 channels Master Hearing Aid.

“Plus” model

The Plus model offers all the features of the Basic, plus Multi Frequency, High Frequency, Bekesy and Masking Level Difference (MLD).

“Plus VRA” model

Piano Plus VRA also features pediatric audiometry capabilities. It can become the heart of a traditional or video-VRA system. Please see the dedicated page for further information.


Piano features two completely separated and independent channels: you can even set different frequencies for Channel 1 and 2.
Furthermore, left-handed operators can set Channel 2 as the main channel.

Embedded speech material

No more CD player headaches! Piano features an integrated 2 GB flash memory for storing your speech material. Dedicated buttons allow you to access word lists with ease. The screen also displays the word currently being pronounced.

The display

Piano incorporates a large high resolution color graphic display, giving a clear and detailed picture of the exam in progress. And with touch screen input, interaction with the instrument is extremely simple and intuitive.

Noah & Daisy integration

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


Piano features Inventis Hy-Tech: you can decide whether to operate it in the traditional way (stand-alone mode) or control it through the computer.
