The Hearing Aid Test System uses, like most TWS Systems, an  Analog-to-Digital converter in a PC. 

A specially designed Two-Channel Preamplifier  with the necessary Power Amps to drive the Testbox,  Microphone Supplies and Attenuators is also part of the system.

Standard Hearing Aid Testboxxes can easily be connected to the system.

For Quasi Free field measurement    a  special Loudspeaker and Software are used separating the direct sound from all room reflections using mathematical methodes. 

This technique makes ist possible to test Hearing Aids with steep directional characteristics without using anechoic chambers.
