[SML] 125Hz room resonance

Hey all,

I've just encountered a problem that I think this group is well equipped to
assist me with. While not directly stagecraft-related, stagecraft (and
audio) knowledge is applicable. I deeply appreciate any advice in advance.

My bedroom seems to have developed a 125Hz resonance (along with one more
significant one at about 33Hz), which seems to have prompted my brain to
give me "observational(?)" tinnitus, which is consistent tone with a
perceived value of about 8KHz. It's very annoying.

I tracked the tone around the room with an RTA and was able to identify a
"hotspot", but it seems that even hanging a heavy soft-surface (woven wool
blanket) has not dampened the problem. I'll also try putting foam behind
the television when I get home today.

Any advice?

Again, TIA!
