The sound detection room in the laboratory is conducted for a single sound source, and there are often many different sound sources around the noise environment. The distance between the Noise Barrier and the sound source, and the distance between the affected part and the Noise Barrier will all decrease. The noise effect has a certain impact, so the actual noise reduction effect of the louver-type sound-absorbing board is between 10-25dB.
The key to Noise Barrier noise management is to master the noise source, receiving point and propagation channel. Apply different technologies to different noise situations, take different measures for different noise sources, and use different methods to solve different noise problems. Therefore, our company draws on the successful experience of similar noise engineering management based on the analysis of the application theory.
Noise Barrier noise reduction method: Noise Barrier noise reduction method is sound absorption + sound insulation. When the sound source passes through the sound absorption panel, it enters the Noise Barrier through the punching partition.
The thickness of the Noise Barrier product is 100mm, filled with sound-absorbing materials, and there is a certain sound-absorbing melting cavity between the sound-absorbing material and the two walls of the Noise Barrier. When the sound passes through the glass wool, the ultra-fine glass wire will fully absorb and reduce the sound. After passing through the sound-absorbing material, the reduced sound will pass through the air melting cavity, hit the back panel and be reflected, and then return to the glass wool to continue to be reduced. In this reciprocating cycle, the noise reduction of Noise Barrier is 36dB according to laboratory measurement.
