1, equipment installation of acoustic enclosure
For the main source of noise mechanical equipment need to reduce noise radiation from the source of noise, add acoustic enclosure, can make other noise management measures to play a greater role in order to improve the overall effect of sound insulation and noise reduction. Due to the type of sound source of various sound source equipment, external dimensions, ventilation and heat dissipation requirements are different, so the need for acoustic enclosure on-site survey, analysis, design programs, processing and production.
2, the equipment room to take sound-absorbing measures
Using sound-absorbing materials to decorate the inner surface of the equipment room, such as walls and roofs, or hanging space in the workshop sound-absorbing body, absorbing the radiation and reflection of acoustic energy, so that the intensity of the noise is reduced. Materials with good acoustic effect are glass wool, slag wool, foam, felt, cotton wool, aerated concrete, acoustic panels, wood wool panels and so on.
3, equipment installation muffler
With a device that can prevent the sound propagation and allow the airflow through the muffler. This is the main measure to prevent aerodynamic noise. Muffler has the use of sound-absorbing materials muffling resistance muffler, according to the filtering principle of manufacturing resistance muffler, as well as the use of the above two principles designed impedance composite muffler.
4, equipment vibration isolation
In order to prevent the spread of vibration noise through the floor and walls and other solid materials, in the foundation of the machine and the floor, wall joints with vibration-damping devices, such as rubber mats, asphalt and so on.
