Unified Acoustics Theory ( by Borat )

[Borat]

prepare for audio enlightenment !

so you know there are 3 frequency regions for the room

top dominated by reverb

middle dominated by standing waves

bottom dominated by room gain

you also know that it is the middle region that is problematic. rather than trying to control the standing waves we can eliminate the region entirely ! by growing the other two regions until they meet in the middle.

there are 2 ways this is currently being done:

1 - dipole speakers substitute the entire room for the back chamber of the speaker. this is essentially like increasing speaker box dimensions by orders of magnitude. the result is that the top or reverb frequency region extends down by orders of magnitude mostly eliminating the standing wave region ( of internal standing waves )

2 - multiple subwoofers section the large acoustical space into multiple smaller spaces thereby decreasing the dimensions of effective acoustical space dramatically. this extends the bottom or pressurization frequency range up from the 20s to perhaps as high as 100 hertz. thereby eliminating most of the standing waves by eliminating a large chunk of the standing wave region itself.

in summary i didn't really tell u anything you didn't know. but i gave you a new and superior way to think about what you do know.

thank you very much.

all bow down before the almighty Borat !

Wow...I think I may have found another enlightening quote from Borat's words of wisdom to reply to this thread.

isn't that what i was saying ? that it should be manipulated ?

Good work

It sounds like Borat has been manipulating it, perhaps the thread should be entitled, "Borat pulled it off".

no lol - other people have ... unwittingly

large venues for example don't have the kind of boomy bass problem that we experience at home - why ? because the problematic region for those venues is well in the infrasound. so increasing room size pushes the top end of the problematic region down.

at the same time increasing the number of subwoofers pushes the bottom end of the problematic region up.

in a large enough room with enough subwoofers the problematic standing wave region will not exist at all.

i doubt it can be as bad as in my room.

why do bathrooms have this tubby sound in your opinion ? sure the fact that there is nothing to absorb ( like furniture ) sound is important. but it is also the relatively smaller dimensions of the bathrooms that push standing waves up into the voice range.

Dipoles excite room modes as well, though often somewhat less than monopoles.

The number of subwoofers has no impact on when room gain starts.

Nice troll though.
