Full anechoic room / mute room


    Summary: anechoic chamber is not only a special laboratory for acoustic test, but also an important part of the test system. In fact, it is also one of the acoustic test equipment. Its acoustic performance index directly affects the accuracy of the test. The anechoic room is divided into full anechoic room and half anechoic room. The six surfaces of the room are all covered with sound-absorbing layer, which is called full anechoic room, generally referred to as anechoic room. Among the six surfaces of a room, only five or four surfaces are covered with a sound absorption layer, which is called a semi anechoic room. The main function of anechoic chamber is to provide a free sound field space or semi free sound field space for acoustic test. The sound absorption treatment is the key to ensure the sound field performance after the completion of the anechoic chamber. Most of them adopt the sound absorption structure with strong sound absorption capacity, such as the sound absorption wedge or plate type thin plate resonance sound absorption structure.

   The fully anechoic room can provide ideal free field environment and very low background noise for electroacoustic testing. It is suitable for testing the electroacoustic performance of speaker, microphone, earphone, speaker, tablet computer and other products. Our company can customize the anechoic room for customers to meet the needs of accurate testing.
