We’ve been surrounded and companied by noise 24×7 as an invisible killer existing except for work pressure in modern life, both considered among civilized society.  Noise is being defined in all terms ending up with unpleasant conditions physically and mentally, leading to frustrating setbacks in all kinds while having a conversation, thinking, rest or sleep.  In health, it could be leading to serious hearing dysfunction impact gradually via exposure under long-term-noise environment.

Simple material but multiple advantages-light-weighted, non-toxic, fire, water and dust-proof, anti-salt erosion, high sound-absorption rate, stain resistance, anti-electromagnetic wave, long duration for enduring, various colour options, and easily cutting or assembling.

Micro perforated sheet with predominant sound absorption function can apply to diverse indoor spaces as well as outdoor acoustical barriers to block outdoor noises ; for examples, traffic noises, construction sites noises or factory noises . With unique feature of no acoustical fiber backing, Micro perforated sheet noise barrier would not attenuate sound-absorption / insulation result under wet weather and circumstances . For traditional perforated noise barrier, its sound reduction efficacy will greatly fall down after its acoustical fiber backing get damped. Simultaneously, acoustical fiber will sink down due to the dampness, which may cause permanent sound-absorptive function decay.
