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。
The air-passage device can adjust the flow quantity and input any required gas randomly.
※气路装置可任意调节流量，能任意输入各种所需气体。
