Mouth Simulator Type AM3000, artificial mouth

Mouth simulator Type AM3000 is a device that approximates the acoustic field generated by the human mouth in the near field. It is used for measuring the telephone transmitters and communication microphones and conforms to the Standards IEEE269 and ITU-T Rec.P51. AM3000 contains high quality of loudspeaker, which mounted in a special enclosure and having a directivity and radiation pattern similar to those of the average human mouth. So AM3000 has a high performance of simulating a stable, wide frequency response and low distortion sound source used for the testing of acoustic transducers.

In practice, the mouth simulator will be calibrated at the MRP position using a special calibration jig AD200, which is designed to hold a 1/2 inch standard microphone at a distance of 25 mm from the lip ring.

The AM3000 can produce a minimum stable SPL of 106 dB in the frequency range 100 Hz to 8 kHz at a distance of 2 5mm from the lip ring, and it can perform within the maximum continuous power consumption of 10 W. The AM3000 will be delivered with a calibration chart, which is giving the frequency response measured at MRP position, and we can also provide the frequency response with equalization in compressor loop.
