Air Compressors

Although recent screw-top compressors have made the industry much quieter than the classic piston compressors, they are still one of the louder pieces of equipment found in industrial environments.

Sound is both structureborne and airborne, and air compression noise presents unique challenges.

Intake (and exhaust) are, of course, essential to the operation of compressors – to reduce noise, you have to treat it without impacting performance.

Piston compressors produce a particularly distinctive pulsing sound, typically with a low frequency signature.

It’s common for that low frequency sound to leak into your structure, causing noise and possibly interference with other machinery. This can be mitigated with a wide range of isolation products.

Typically, you want to either box your compressors in or mount them to isolate their vibrations.

First, examine your compressor’s enclosure itself. This can often benefit from heavier barrier composites, such as vinyl foams, which are especially good for low frequency noise.

  • Best Bet: 2lb vinyl in 2 – 3″ thickness (2″ is a good bet). You can also get specific recommendations from our experts based on the equipment operating profiles.
