The size of a compressor room, the location of the compressors inside the room, and the materials used to build the room are all key factors in determining and creating (and decreasing) compressor noise. The transfer of vibration through the compressed air pipe system can also have an effect on the transport of sound throughout a facility. To assist reduce noise to a minimum, it is necessary to equip a compressor and pipe system with adequate vibration and sound insulators, or even encapsulate piping portions within a sound absorbing substance. Many stationary air compressors also include built-in noise-cancelling systems.
In addition to these suggestions, here are four other effective ways to reduce noise and make the workplace safer and more enjoyable:
Soundproofing. This is accomplished by erecting an acoustic barrier between the sound source and the receiver. This means that depending on the barrier and its particular features, only a portion of the sound may be insulated. Obviously, a larger, heavier barrier will be more effective than a smaller one.
Absorption of sound. There is an additional level of sound reduction provided by surrounding the sound source with porous adsorbents attached to a barrier, in addition to that provided by insulation alone; consider open cell polyurethane foam or heavier cloth applications.
Insulation against vibration. By preventing vibrations from being transferred from one area of a structure to another, you may lower sound levels as well. A large piece of machinery passing through the floor is a common source of vibration transfer. Steel springs, cork, plastic, and rubber are all good materials for minimising this transfer and related noise. The material used is determined by the machine’s dimensions and surrounding space, as well as the machine’s stability requirements. Keep in mind that if the compressor is installed in a location where it will come into contact with another object, the noise generated by this contact will quickly multiply.
Vibration reduction. Fitting a structure with an exterior dampening surface made of elastic material is an efficient way to reduce machine vibrations (and sound). The more efficient the damping barrier’s ways of decreasing vibrations, the thicker it is. This may be the most cost-effective approach, but it will produce the most restricted outcomes.
