Ventilation ducts Noise Control "Seles' most powerful noise damping business

Ventilation ducts Noise Control "Seles' most powerful enterprises in Suzhou Seles noise damping shock absorber Co., Ltd. is a design, development, manufacture, sale, installation and maintenance as one of the modern professional damping noise reduction company, is one of China's main domestic cushioning products supplier. Main products: spring shock absorber rubber shock absorber hanging seat cushion shock absorber damping spring shock absorber shock absorber soft rubber joints metal compensation metal hose pump shock absorber compression damper fan Machine damper damper generator cooling tower wind chassis damper damper damper air conditioning heat pump air conditioner damper damper damper ceiling fan damper centrifuge textile machinery damper die machine shock absorber great harm to humans because of the noise, so people through in-depth study of the noise, summed up many methods of noise control, are summarized as follows: a method of noise control: active noise reduction. Active noise reduction is the use of computer technology, based on the noise of the sampling frequency, amplitude, period, etc., and generates near synchronous inverted signal superimposed to achieve the purpose of noise control. Currently, this type of noise control method is not mature enough, in the research and development stage. Noise Control Method two: passive noise reduction. Most noise reduction methods are passive noise reduction. In accordance with the use of materials and parts can be divided into vibration noise control, acoustic noise control and soundproofing noise control. In most cases, a variety of methods are usually combined use. According to the current material technology and construction techniques, basic can control any noise. Beijing Branch source of sound noise control engineering and technology Equipment Co., Ltd. adopt measures to control the sound output noise source, the control of noise propagation and reception, to give it the desired acoustic environment, namely noise control. Using a variety of noise control methods can receive different noise reduction. As ordinary gear mechanical transmission parts changed elastic sleeve gear, it can reduce noise 15 to 20 db; caulking into welding, forging into the friction pressure processing, generally 30 to 40 db noise reduction. Select control measures and reasonable measures to control noise is based on the cost of noise control and noise standards to allow the relevant factors, labor productivity such as a comprehensive analysis determined. Control of environmental noise control technology is the basic means. Administrative measures and proper planning are also very important. Noise control technology basically all of the noise problem can be divided into three parts: source - transmission - receiver. Thus, the general noise control techniques are divided into three parts to consider. The first is to reduce the sound source of the noise, if you can not do, or can do but not the economy, is considered to reduce the spread pathway. As the above scheme still meet the requirements of noise control or uneconomical may consider the recipient's personal protection. (1) sound source control reduces noise source itself is the ultimate solution; (2) the transmission of noise control; (3) the absorption: the main use of sound-absorbing material or absorbent structure to absorb acoustic energy; (4) Noise: with sound shield block, isolate, is one of the most effective measures to control the noise; (5) muffler: muffler is the use of mufflers to reduce the spread of sound in air.
