Wedge:The acoustic absorptivity of sound-absorbing materials used in anechoic chamber must be greater than 0.99. In anechoic chamber, gradient absorption layer, wedge or conical structure are often applied with glass wool and flexible foam as its sound-absorging materials.
Anechoic Door: The design of rotatable door can affect the whole function of anechoic chamber. Therefore, it's crucial to combine steel plate and sound-absorbing cotton in the door, which is exactly our design.
Acoustic Insulating Material:Applying high-density materials to enclose external noise.
Damping materials: Using spring, rubber and cotton to enhance damping capacity.
The Anechoic Chamber conforms to GB/T 6882-86 and ISO 3745 specifications.
