Workshop silencer housing suitable for industrial production sites

LB-3B workshop silencers room noise pollution is one of the major pollution, it prevents people talking, thinking, learning, gives rise to an unpleasant sensation. Noise reduction methods: (1) reduce the acoustic noise way to control the spread of noise, change the noise transmission source has been issued, such as the use of sound-absorbing, sound insulation, sound barriers, isolation and other measures, as well as urban planning and rational building layout. (2) reduce the noise sound source, industry, transport can use low noise production equipment and improve production technology, or change the movement noise sources (such as damping, vibration isolation and other measures to reduce the solid body of sound). When acoustic measures (3) by the tone or by noise protection organ sound, unable to take measures on the sound source and transmission, or take still can not achieve the desired results, it is necessary for sound by sound or by an organ to take protective measures , such as long-term occupational noise exposure of workers to wear earplugs, earmuffs or hood 1. basic approaches and principles of noise control: Before the noise reaches the eardrum, using the latest technology ,, use damping, noise, sound absorption and layout of the building and other measures to try to reduce the vibration of the sound source, the propagation of sound energy absorbed, or obstacles all or part of the sound is reflected off. 2. range generator room noise control, air compressor room, cooling towers, industrial refrigeration room, central air conditioning room and other industrial production sites, Kara OK, dance halls, theaters, office buildings and other cultural entertainment.
