I would spend the money on a California Air Tools quiet compressor or other type of muffled compressor. When our 80 gallon 2 stage fires up at work it's deafening. When my California Air Tools compressor fires up at home you can barely hear it. I know they make sound cabinets for them too. Their 60 gallon compressor runs at 75 dB. My compressor is 55 dB IIRC.
