Test & Measurement

Fonix Testboxes from Frye Electronics

A hearing aid testbox is a specialised device which enables the frequency response, distortion and output level of a hearing aid to be measured.

Frye, the makers of Fonix test boxes, now include with composite tone versions of their test boxes, a Digital Signal Processing (DSP) test signal, designed specifically to test digital hearing aids with signal processing. Previously the testing of this type of aid has been a major problem. In the presence of the traditional pure tone or composite tone digital aids are likely to change their characteristics making test results meaningless.

The new test signal, which displays the response curve in real time, also makes the setting up of Radio Aids for use with hearing aids, whether linear or non-linear, much quicker and more straight forward.

With digital aids being the norm, we therefore recommend that all test boxes are ordered with the composite tone option to take advantage of the new DSP test signal.
