Short Circuit Protection Mouth Simulator

Product Description

MOUTH SIMULATOR
Mouth Simulator are high-performance artificial mouths conforming to ITU-T Rec. P.51 and delivers highly accurate and repeatable electroacoustic measurements.

MOUTH SIMULATOR are designed to test telephone transmitters, smart speakers, and other microphones where a sound field similar to the human voice field is required.

The Mouth Simulator also provides a reference source for near field testing of handsets and microphone based devices, in smart devices. The artificial mouth simulator closely replicate the sound field generated by the human mouth, as specified in IEEE 269 and
ITU-T Rec P.51 - fulfilled by both MOUTH SIMULATOR.
USE SCENARIOS
Quality control testing of frequency response and distortion of telephone transmitters and close-talking microphones
A sound source for acoustic measurements
Testing of smart devices, phones, speakers, etc
Provision exists for fitting a microphone at the mouth opening, for use in a compressor loop to give constant sound pressure output. Accurate calibration is facilitated by a calibration jig provided with this product.ITU-T Rec P 51 Mouth Simulator Accurate Repeatable Electroacoustic Measurements 0ITU-T Rec P 51 Mouth Simulator Accurate Repeatable Electroacoustic Measurements 1
