The simulator mouth is a sound source used to accurately simulate the sound of the human mouth. It can be used to measure the frequency response, distortion and other acoustic parameters of transmission and communication products such as mobile phones, telephones, microphones, and microphones on Bluetooth speakers. It can provide a stable, wide frequency response, low distortion standard sound source for testing. This product fully complies with the requirements of relevant international standards such as IEEE269, 661 and ITU-TP51.
