Rick,

Thanks. I’m looking for user perception.

I can look at test data (Fine Woodworking):

Fein – 65.5 dB
Festool – 58.5 – 68.5 dB
Rigid – 75 – 78.5 dB
ShopVac QL – 72 – 74.5 dB.

They say a 10 dB increase will double the loudness.

I need to make a trip to HD and get them to turn on the vacs.

Thanks again.
