Acoustic Time Reversing Mirror(TRM) can be implemented with an array of transducers that listens to a remote sound source and then transmits a time reversed version of what was heard.

声学时反镜是指由收发合置的换能器组成的基阵对声源信号进行接收、时间反转和再发送，时反后的信号会在声源处实现聚焦。

After a white noise signal has been taken as the input of a standard sound source, a static acoustic test is conducted for a prototype silencer without air flow and at the normal temperature.

采用白噪声信号作为标准声源的输入信号，在常温无气流条件下对消声器实物模型进行了静态放声试验。
