Overview
The Bruel & Kjaer 4128-C Head and Torso Simulator (HATS) is a sophisticated tool designed for in-situ electroacoustic testing of various audio devices. It features built-in ear and mouth simulators that accurately reproduce the acoustic properties of an average adult human head and torso. This simulator is ideal for testing telephone handsets, headsets, audio conference devices, microphones, headphones, hearing aids, and hearing protectors.
Key Features
- Realistic reproduction of human acoustic properties
- Includes Right Ear Simulator and Mouth Simulator
- Adjustable neck for realistic posture simulation
- Complies with ITU-T Rec. P.58, IEC60959, and ANSI S3.36-1985 standards
- Optional Left Ear Simulator for binaural measurements
Specifications
The 4128-C model comes with a Right Ear Simulator Type 4158-C and a Mouth Simulator. A Left Ear Simulator Type 4159-C is available for binaural measurements. The simulator's neck is adjustable, allowing for the positioning of the head in various realistic postures. This feature is particularly useful for measurements in car seats or other specific environments.
Applications
The 4128-C HATS is used extensively in the testing and development of audio devices to ensure they meet the required performance standards. Its realistic simulation of human acoustic properties makes it an invaluable tool for manufacturers and researchers alike.
