How To Reduce Noise By Sound-absorbing Materials

Sound-absorbing materials play a very important role in reducing indoor noise and improving indoor sound quality, and are receiving more and more attention. There are many types of sound-absorbing materials, with different materials, different appearances, and different structural sound absorption coefficients. The number of sound-absorbing materials can be determined according to calculations during use. When selecting specific materials, both sound absorption and aesthetic requirements must be considered. Generally, dry wall sound absorption is to lay the sound-absorbing material on the light steel keel and the cavity between the keel to form a sound-absorbing structure system, such as: sound source wooden sound-absorbing panels, polyester fiber sound-absorbing panels, wood wool sound-absorbing panels, etc. A better choice for decoration and acoustic design. Since the conference hall uses short reverberation, a strong sound-absorbing structure must be used. Because of the strong sound absorption treatment, architects often use various shapes that are prone to acoustic defects, such as round, elliptical, oval, and dome-shaped roofs. The measures to control the sound quality defects, in addition to the configuration of the diffusion structure, usually use a strong sound absorption method, because it also plays a role in controlling the reverberation time.
