I have two air compressors and both of them are very loud and noisy when they are running. One is a two horsepower home-shop unit and the other is small fractional horsepower inflator. Why can't they build silent, or at least quiet, air compressors? I mean what is making all that racket anyway? It's not like there is combustion or any other intrinsically noisy operation going on.
I did a little search on Google, and there are silent air compressors available. One guy made a hobby unit using an old refrigerator compressor. Those are certainly quiet enough. You often don't even notice if it is running or not. Compressors for dentists offices seem to another popular item. Of course they are more expensive.
It looks like manufacturers of regular air compressors are starting to realize how obnoxious their products are and are starting to do something about it.

Howdy...
You are quite correct. Very quiet air compressors are available (Jun-Air makes an exceptionally quiet unit)but they are quite expensive.
One of the costs associated with low cost compressors is that they are noisy. You pay through the ears!
I write a site about air compressors and there's lots of info on this subject there: www.about-air-compressors.com.
