Best sound insulation for a compressor

[nicobkn]

Hello folks!

I just moved in a new place and I have to build something for my 60G compressor. Budget is tight, I will be storing my compressor under my stairs. I need something that will bring the noise down, a lot.

What are your thoughts ?

I've seen a lot people that said simply putting a muffler on the intake helped a lot. I'm curious what other people suggest as well since I think I need to do the same.

I insulated the small closet mine was in. Also has large vents for outside air. Shut the door and run it.

The best way to control noise is to control the source. A muffler will be the most effective way to quiet it. If that's not good enough, then you can start treating the room.

Sound insulation also means heat insulation in most cases. Most fiberglass is only going to be effective at 1kHz and up. The thicker it is, the better it will absorb lower frequency stuff. For low frequency, you really need to add mass ($$; block walls with sand; double independent walls with airgap). I'd start with some nice fiberglass 3"+ thick and see how that works. If there's still some uncontrollable low frequency drone, you'd have to do something different in addition to the fg.

Be careful with vent placemen if you are using some. A vent that's even only 1% of the wall size can have a detrimental effect on the effectiveness of the wall in isolation noise. If you find a vent is necessary, place it on the wall entering the room of least impact.

I used fiberglass batt in the wall cavity and covered the outside of the wall studs with Quiet Brace.

how they do it for commercial buildings
Give ya some ideas

There is a product called Acoustiblok that is designed to reduce noise. It is better than fiberglass for sound reduction.

Mineral wool insulation.

Make sure you have adequate ventilation. I would but a combination smoke/CO2 sensor i n that closet it, or outside next to a high vent.

I knocked 5 dB off the noise of mine with a pair of Solberg filters.

the best sound insulation is the same material corks are made from! you know wine corks!

The shop I work at has the compressor in a storage room between the office and bays. He has 2 or 3 sheets of 2 inch foam boards around three sides of the compressor. It takes some of the noise out

Go to the acoustiblock site and see the results for yourself.

I'm sorry, but no. Maybe for backing on a floor, but not for a wall treatment. There are much better options. Every material has it's advantages and you usually have to use multiple treatments for a wide frequency range. There is no single 'best' treatment.

Depends on the frequency range and the installation. A combination of both is the better treatment.
