The 8000 Hearing Aid Test System performs a broad range of hearing aid measurements from basic, everyday tests of distortion, battery current drain, and frequency response to advanced tests of digital processing delay and phase. The FONIX 8000 is composed of a main electronics module with a front panelfor controlling the operation of the analyzer and a wide-format thermal printer. An external video monitor is used to view test results.

The FONIX FP35 provides quick, accurate information about how well a hearing aid works. It uses a graphical display or numerical table to show how much amplification the aid provides, which frequencies it amplifies, and how much distortion is creates. The FP35 analyzer is meant to be used primarily by hearing health professionals who fit hearing aids on hearing-impaired adults and children throughout the world.
