Going from 58 db to 82 db in musical notation is equivalent to "ppp to fff",
or an orchestra playing about as soft as it can (ppp) to as loud as it can
(fff). A big difference. Some reference levels are given at
http://www.coolmath.com/decibels1.htm. 58 db is awfully quiet.

Fein Turbo II is rated at 58 decibles. The Shop Vac "Quiet Deluxe 6.5
HP" is rated at 82 decibels.

The rule of thumb I know is that 3 decibles corresponds to a doubling.
Thus the Shop Vac Quiet Deluxe 6.5 HP is 24 decibels louder, or 3 db +
3 db + ... + 3 db (8 times), or 2x2x2x2x2x2x2x2 = 2 to the 8'th power =
256 times louder.

Is that correct? If so, holy moly!
