noise control barrier material， acoustic sound barriers A sound barrier is a device inserted between the sound source and receiver. When a sound barrier is found, three phenomena occur: reflection, transmission and diffraction. Sound waves can only diffract from the top of the barrier and form a sound shadow area behind the barrier. In this sound shadow area, people can feel that the noise is significantly reduced, which is the noise reduction effect of the sound barrier. It will not cause performance degradation or abnormal quality due to rain and temperature changes, and guarantees service life.

noise control barrier material， acoustic sound barriersThe construction period is short, saving engineering costs. Various color paintings can be used to coordinate with the environment to create beautiful scenery. The materials used are all non-combustible materials, which fully comply with the requirements of environmental protection and fire protection standards, and the fire classification reaches Class A. The prevention and control of railway noise pollution generally adopts three methods: sound source control, sound source control, sound source control, sound source control and sound source control. Sound transmission mode control and sound receiving point protection. Soundproof point protection includes the function of protecting the soundproofing of buildings and changing sensitive points. It achieves an effect that other noise reduction methods cannot replace.
