MICROPHONE TEST MODULE AND A METHOD OF TESTING MICROPHONES

A test module for testing microphones comprises an outer chamber being airtight, and a sound chamber comprising an electrical test device for testing the microphones. The sound chamber is located within the outer chamber, and the sound chamber is coupled to the outer chamber with a connection suppressing structure-borne noise between the outer chamber and the sound chamber. A space between the outer chamber and the sound chamber has a gas pressure being lower than an ambient air pressure. A method of testing microphones comprises evacuating the space between the outer chamber and the sound chamber to create a lower gas pressure than an ambient air pressure, and testing the microphone. 一种用于对麦克风进行测试的测试模块，包括：气密的外室；以及声室，该声室包括用于对麦克风进行测试的电气测试装置。声室位于外室内，并且声室通过外室与声室之间的抑制结构传播噪声的连接而耦接至外室。外室与声室之间的空间的气体压力低于环境空气压力。一种对麦克风进行测试的方法，包括：将外室与声室之间的空间抽空成具有比环境空气压力低的气体压力，并对麦克风进行测试。
