The anechoic chamber is mainly composed of a series of sound insulation and sound absorption materials. It is designed and manufactured for ground vibration isolation, wall sound insulation and sound absorption, ceiling sound insulation, soundproof doors and windows, etc. to meet the required noise elimination effect.

The sound involved in the acoustic effect of the anechoic chamber includes environmental noise and the background noise value in the anechoic chamber. The greater the difference between the inside and outside, the higher the noise elimination design requirements. In order to achieve the ideal effect in the anechoic chamber, it is necessary to design the scheme from three aspects: vibration isolation, sound insulation, and sound absorption.

1. First of all, the overall vibration isolation. The footsteps on the ground, the vibration of the machine operation, the sound of piling, etc. will be transmitted into the room through the ground. In order to prevent these sounds from entering the anechoic chamber, the ground needs to be "suspended" and damping shock absorbers are installed under the floor.

2. In addition to vibration isolation, the wall thickness needs to be designed according to the difference between the internal and external noises, and the sound absorption and sound insulation are used to meet the wall. The ceiling and the wall are made in the same way.

3. In order to achieve better sound absorption effect, sound insulation cotton, sound absorbing spikes and other materials will be installed in the anechoic room to achieve the ideal sound insulation effect.

The above is a brief description of how the anechoic room is anechoic. The core is to achieve the sound insulation effect through a series of sound absorbing, sound insulation and noise reduction materials.
