Anyway...the term "standing wave" is misleading as the pressure wave still moves through the air. If it did not then we would hear no sound. The practical point is that the energy from waves at certain frequencies (determined by the dimensions of the room) combines with itself resulting in notes at these frequencies sounding too loud. An effective acoustic treatment needs to absorb enough sound energy to result in a room that has an even response across the frequencies. There are various ways of doing this, which is what I am interested in.

One thing about a standing wave is that it doesn't really "move" through the air. Even so, one can still hear sound that exists in standing waves (unless one is at a node).

Or too soft, (or even occasionally the right level, and other points inbetween) depending upon where one is in relation to the wave's cycle. Standing waves also can have different dynamic characteristics from the travelling wave component of what you hear. This can possibly most obvious with frequencies which "ring" or hanging on/decay more slowly (amongst other effects) in comparison to other frequencies.

Me too :)

You're making a fair and important point which, for the record, I completely agree with, but you're not making it like the polite, friendly and considerate chap I know you are. I know it's important and we share some very strong feelings on health and safety matters but you still need to make the point properly or you undermine it's validity.
Now be a good boy or Santa won't be bringing you a nice new PC to replace all those dodgy old Macs ;) :bouncy: 0VU :) ***

It's a fair cop Guv..... But santa can take his poxy P(iecesof)C(rap) and shove them right down the throat of Steinbugs support.....

Not being terribly dyslexic, I sold my soul to a less Xmassy anthropomorphic personification.

yep - food - sooner the better. Though I've a sneaking feeling that it'll have to wait until after Christmas, what with all the "I must have it finished for Christmas" comments that I keep hearing :roll: Half of them from people who haven't even started yet! Oh, and the first person to mention bass traps pays for pudding! :headbang:

And repeat after me...."PC means Proper Computer, Mac means raincoat" :tongue: ;)

I'll get me Mac :tongue: :beamup:
