AM 591 Artificial Mouth
Ultrasound
Comply with the requirements of IEEE269661 international standard and ITU-T P51
recommendations for transmitting sound signals using the "mouth reference point"
Ultra wide frequency range
Acoustic measurement standard sound source
Low distortion, high stability
Overview
AM 591 ultrasonic artificial mouth is used to accurately simulate the sound source of the sound field near the human mouth, and is suitable for testing acoustic parameter indicators such as frequency response and distortion of telephone transmitters and microphones (microphones);
AM 591 has extremely high sensitivity and broadband energy conversion efficiency, ensuring extremely low distortion at a sound pressure level of 94dB even at a working distance of 6cm; At a typical 2.5cm MRP distance and 94dB sound pressure level,
Distortion energy from 700Hz to 60kHz;
Less than 1% with Megson PM 0083 preamplifier, excellent performance, suitable for R&D testing or production testing of high-end audio products.
