I'm building a box to hold a small compress. Purpose is to mask as
much of the compressor sound as possible. Of course, the compressor
will need to have air intake and output availability.

Can anybody recommend a filter or filter material that reduces noise
transmission but still allows air to pass through it?

Thanks

I have a large air compressor. It is in the attached garage. I piped it down
to my basement work shop. Cannot hear it run. WW
