The 4128-C is vibration and sound equipment from Bruel & Kjaer.
Additional 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
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.
The Bruel & Kjaer 4128-C Head and Torso Simulator 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
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.
