Audiometry for Teaching Experiment in PowerLab Systems

The aim of this work is electronics device for audiometry measurement construction. Presented electronic device is designed as extension of ADInstruments teaching experiments PowerLab systems. Realized audiometer is suitable for standard medical testing of hearing with step by step measurement and output protocol arrangement. The original hardware design consist primary from extension electronics board containing precise tone generator and auxiliary input. Realized audiometer device can be also used as stand alone device possible supplemented by LCD outputs, I/O control panel and feedback pushbutton. Application of this device introduce accurate and reliable hearing condition testing.
