High-frequency Head and Torso Simulator (HF HATS) provides unprecedented realism, for electroacoustic testing of smart devices and speakers, audio conferencing devices, microphones, headphones, and hearing aids.

High-frequency Head and Torso Simulator (HATS) Type AD8300 family, with built-in realistic ear and mouth simulators, provide a realistic reproduction of the acoustic properties of an average adult human head and torso. High-frequency HATS is designed for in situ electroacoustics tests and can cover the full audible frequency range (up to 20 kHz).

USE SCENARIOS

Testing of smartphone audio performance in relation to national and international standards for communication quality. This includes testing of mobile and wireless handsets

Evaluation of the intelligibility of headset two-way communication in the presence of background noise and conditions that may produce feedback into the system

Evaluation of speech intelligibility in two-way communication using hands-free devices such as conference phones and smart speakers based on accurate production of human speech for the evaluation of directivity, intelligibility, feedback and background noise suppression

Facilitates the evaluation of microphone recording accuracy for human speech with variations in level, directivity and sibilance

Measurement of the audio response of headphones in exactly the way a human would perceive the quality. This allows designers to identify and correct anomalies in headphone design that lead to artefacts in the frequency response. The new ear canal design provides the most benefits to designers of in-ear headphones, where the geometric fit is crucial to the evaluation

Sound quality evaluation of hearing aids with correct anatomical positioning

Measurement of the attenuation and effective sealing of hearing protectors with the correct ear canal geometry and head anatomy
