Harp is an advanced diagnostic audiometer, capable of performing fast and accurate air, bone and speech audiometric exams, as well as several additional tests including a two-channel master hearing aid.
Top-level features combined with ease of use and portability make Harp the ideal choice for a wide range of users, from hearing aid dispensers to audiologists, clinics and hospitals.

The models

Harp is available in two configurations to suit different user needs: Basic and Plus. Harp Plus features a wider test battery and an internal flash memory, where you can store the pre-recorded speech material.

The test

Besides the standard threshold exams, Harp also performs Hughson-Westlake automated audiometry, speech audiometry, ABLB, SISI and Stenger exams. In addition, the “Plus” model features DLI and Tone Decay tests and includes a 2 channels Master Hearing Aid. TEN test and QuickSIN are available upon request.

Embedded speech material

No more external player headaches! Harp Plus 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

Harp features a large, bright graphic color display, on which you can view the complete audiogram during the examination.

Portable system

Despite its top-level features, Harp is ultra-compact and easily transportable. It even comes with a dedicated carrying case (optional).


Simply connect Harp 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.


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