What causes air compressor noise?

All machines generate sound and vibration, so do compressors. Their noise level can be influenced by the properties of the room it is in, the room's size for example. In this article we will discuss this further, as well as give you five methods on how to reduce it. Learn more about the basics of sound here.

How to reduce sound

There are five different ways to reduce sound. 

  • Sound insulation: Sound insulation involves an acoustic barrier being placed between the sound source and the receiver. This means that only a part of the sound can be insulated, depending on the area of the barrier and its insulation characteristics. A heavier and larger barrier is more effective than a lighter, smaller barrier.
  •  Sound absorption: involves the sound source being surrounded by light, porous absorbents attached to a barrier. Thicker absorbents are more effective than thinner absorbents and typical minimum densities are approx. 30 kg/m3 for open-cell polyurethane foam and approx. 150 kg/m3 for mineral wool.
  • Vibration insulation: is used to prevent the transfer of vibrations from one part of a structure to another. A common problem is the transfer of vibrations from a built-in machine to the surrounding sound insulation barrier or down to the floor. Steel springs, air springs, cork, plastic, and rubber are examples of materials used for vibration insulation. The choice of materials and their dimensioning is determined by the frequency of the vibration and by the demands of stability for the machine setup.
  • Vibration dampening: involves a structure being fitted with an external dampening surface composed of elastic material with a high hysteresis. When the dampening surface applied is sufficiently thick, the barrier wall will effectively be prevented from vibrating and, consequently, from emitting sound.
  • Dampening of a sound source: will often influence its operational behavior. It may give limited results, yet provide a viable solution in terms of cost.
