In the actual engineering, the free space of the acoustic field is the key to the identification of the sound chamber.. National standard ISO 4745 and 6882-86 GB provided identification method for the free space of the room for the free space of the room for identification.
另外,本底噪聲是消聲室的另一個重要指標。測量中得到的本底噪聲是儀器的本底噪聲加消聲室的本底噪聲。
In addition, the background noise is another important indicator of the silencing chamber.. The background noise in the measurement is the background noise of the instrument and the noise of the background noise of the noise and the noise of the room.
