Background
The anechoic chamber is not only a special laboratory for acoustic testing, but also an important component of a testing system, and is actually one of acoustic testing devices, and the acoustic performance index of the anechoic chamber directly influences the testing precision. The anechoic chamber is divided into a full anechoic chamber and a half anechoic chamber. The complete anechoic chamber is formed by laying sound absorption layers on six sides of the room, and is generally called anechoic chamber for short. The sound absorption layer is laid on only five or four sides of the six sides of the room, and the room is called a semi-anechoic chamber. The main function of the anechoic chamber is to provide a free or semi-free sound field space for acoustic testing. The sound absorption treatment is the key for ensuring that the sound absorption chamber can obtain good free sound field performance after being built, and most of the sound absorption chamber adopts sound absorption wedges or flat plate type thin plate resonance sound absorption structures with strong sound absorption capacity.
Refers to a room without reflections. And sound-absorbing materials with good sound-absorbing performance are paved on the walls of the anechoic chamber. Therefore, the reflection of the acoustic wave does not occur indoors. The anechoic chamber is specially used for testing sound boxes, loudspeaker units and the like.
The sound absorption material used in the anechoic chamber requires that the sound absorption coefficient is more than 0.99. Generally, a gradual change absorption layer is used, a wedge or cone structure is commonly used, glass wool is used as a sound absorption material, and soft foam plastic is also used.
