Head and Torso Simulator (HATS) - Type 4128D

Head and Torso Simulator Type 4128D is a mannequin with built-in ear and mouth simulators that provides a realistic reproduction of the acoustic properties of an average adult human head and torso. It is ideal for performance in-situ electroacoustic tests on:
telephone handsets (including mobile and cordless)

• headsets
• audio conference devices
• microphones
• headphones
• hearing aids
• hearing protectors.

Features

• Complies with ITU-T Rec. P.58, IEC60959 and ANSIS3, 36-1985
• Highly representative mouth simulator with overload protection
• Supplied standardised Right Ear Simulator Type 4158C fulfils ITU-T P.57 and IEC60711
• Optional Left Ear Simulator Type 4159C
  Note: Type 4159 C can be fitted to Head and Torso Simulators with serial number 1947214 or higher (from February 1997)
• Adjustable neck angle for realistic hands-free telephone measurements
• Soft pinnas

Handset Positioner for HATS - Type 4606

Handset Positioner Type 4606 allows accurate and repeatable mounting of telephone handsets on HATS in both standardized and user-defined positions. This makes HATS into a state-of-the-art telephone test rig providing both an artificial mouth and ear with pinna for measurements according to ITU-T recommendations.

Features

• Supports almost all telephone handset designs, including handsets with antennas and asymmetrically mounted transducers.
• Positioning on both ears for left- and right-handed user simulations.
• Ear-centered reference point allow easy 3-D pivoting of telephone mouthpiece.

Handset Positioner Table for Type 4606

This table has been developed to provide a convenient means of noting down all measurement parameters to make measurements repeatable to a high degree of accuracy. The table provides fields for all the parameters with graduated scales on them. The points at which readings should be taken are arrowed on the diagrams in the table.
