Anechoic Chamber
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.

Building Acoustics
Measurements to evaluate and improve Building Acoustics are typically made to analyze and design noise control from room to room, or from outside to inside. Noise sources such as music systems, televisions, appliances, traffic, aircraft, and manufacturing are all around us. The field of Building Acoustics evaluates and designs the materials and methods to insulate and isolate us all from these sound sources when we are at work, rest, or enjoying leisure time. The resulting data is useful for evaluating compliance with building codes and for proposing countermeasures for areas of concern. These measurements often involve creating and measuring an artificial sound source, and then measuring the resulting noise in receiver locations.

Acoustic Calibrators
When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.
