Remember that the dB loudness scale is a logarithmic scale.  That means that a compressor that makes 70 db is twice as loud as one at 60 db.  For each 10 db the sound level doubles.

The Porter Cable I now have makes 82 dB.  It is a little more than 4 times louder than the 60 dB units Chuck found.

Just ordered the California Air tools compressor. Will do something like Mark's drier install.

Edit:  Perhaps install just the California Air Tools motor and compressor since we have plenty of tanks:

California Air Tools SP-9413 1.0HP Ultra Quiet and Oil-Free Air Compressor...
Good idea, except that you can buy the complete compressor unit from Walmart for less money.  Then just cannibalize the parts you want to use, like the motor/compressor and regulator and switch + wiring.  Save the tank for another project!  :))  (there's always another project)

Thinking about Don's question about achieving a long length of flow line between the compressor and the dryer, how about using a "universal" aluminum auto air conditioning condenser?  That would give you a long flow length in a small space.  You could mount it horizontal on the storage bay ceiling where it would be out of the way.  Even have a small fan blowing through it if you wanted to get fancy...

I have considered that option, or rather a new old stock oil cooler that I happen to have from a Mazda R100 rotary engine... just unsure about the max psi these units can handle. I would like greater than 150 psi so that a 150 psi safety poppet valve would protect the system. I love the quiet compressor... I wonder if the 120 psi limitation is the tanks or the pump (or both). The 120 psi limitation would make filling the tires very tiresome :D

A/C condenser will go over 200 psi. Junk yard item then pressure check.

Agree, if you are trying to fill a tire from empty.  But if you are just adding a few psi to make up for seepage, then having the wet tank at 120psi should be adequate.  I run our tires at 100psi, and I can use the coach air hose to top them off with 120psi in the wet tank - no problem.

The same company makes a somewhat less "quiet" 150psi compressor with twice the CFM flow rate, but it's kinda pricey:

On the Amazon site, if you click on different HP ratings the Db level changes on the description.
58 for the 3/4 hp model.  My 91 (which has no HWH system) came with a 120VAC 3/4 hp Gast compressor as OEM.
