Interestingly the peaks of sound are only slightly raised above normal
level - it is the dips that are the big problem, with some frequencies
almost vanishing at some points on the room. If you had a hum problem
at some positions, you had a hum problem, full stop. Just at many
places in the room you couldn't hear it.

Playing a low frequency sine wave is always a revealing way of
assessing a room. Just play it and walk around - very depressing in
99% of rooms.

Last place I had was a large Victorian flat where the living room was near
a perfect cube, and some speakers produced near enough no audible bass.
Worst offenders were a pair of Tannoy Autographs which are massive corner
horn loaded devices. But no bass whatsoever. Go out into the hall, and the
house was shaking with it...
