An Anechoic Chamber is not only a specialized laboratory for sound testing but also an integral part of a testing system. It plays a critical role in the accuracy of sound performance tests. Anechoic chambers are divided into two types: fully anechoic chambers and semi-anechoic chambers. A room with all six walls covered with sound-absorbing material is called a fully anechoic chamber, commonly known as a "no-reflection room". A room with sound-absorbing material on five or four of the six walls is referred to as a semi-anechoic chamber. The primary function of the anechoic chamber is to provide a free-field or semi-free-field sound testing environment. The sound absorption treatment is key to ensuring good free-field sound performance after constructing the anechoic chamber. Typically, wedges or resonance-absorbing structures with flat panels are used for efficient sound absorption. A fully anechoic chamber offers an ideal environment with extremely low background noise for electrical performance testing. It is suitable for testing the acoustic performance of various products such as speakers, microphones, headphones, external speakers, tablets, and more. Our company offers customized anechoic rooms to meet the precise testing needs of our clients.
