Anyway; with apologies for all the technical stuff, you won't hardly
notice the difference between 53 dbs and 50 dbs.

The tech stuff is interesting. One thing not mentioned though, is the
pitch. The loudness is only of factor in determining if a noise is going to
annoy you. High pitched squealing type noises can drive you nuts no matter
how quite as apposed to a low toned louder rumble.
