Keep in mind that the dB scale for sound is logarithmic. A 70 dB compressor is 10X the noise of a 60dB compressor. Normal conversation is 60dB. If I were buying another compressor I would look at the California brand as they are advertised at 60dB. My Campbell Hausfeld 6 gallon in the garage is acceptable to me at 68 dB, much quieter than my CH 5 hp 26 gallon compressor which is why it went to the shop.
