4128 – Head and Torso

Provide the correct simulation of acoustic fields

Head and Torso Simulator (HATS)

Head and Torso Simulators Types 4128-C and D are mannequins with built-in mouth simulators and calibrated ear simulators (according to IEC 60318–4/ITU-T Rec. P.57 Type 3.3) that provide realistic reproduction of the acoustic properties of an average adult human head and torso. They are ideal for performing in-situ electroacoustic tests on, for example, telephone handsets (including mobile and cordless), headsets, audio conference devices, microphones, headphones, hearing aids and hearing protectors.

Handset Positioner for HATS

Handset Positioner Type 4606, with pressure/force and position read-outs, allows accurate, repeatable mounting of telephone handsets on HATS in both standardised and user-defined positions. This makes HATS into a state-of-the-art telephone test rig for measurement according to ITU-T recommendations.
