Quote:

say you have a 6" speaker and you are going to play it at a fixed amplitude (stroke),
to play a very low frequency wave of say 100 hz the cone moves back and forth 100 times per second

now to play a high frequency sound say 10,000 hz the cone moves back and forth 10,000 times. so the cone travels 100 times as far to produce the HIGH frequency sound.

please explain how this uses less energy than the low frequency?

Dunno if you read my post coz yours was up when i finished my novel, but my theory is;

It doesnt. BUT - say the fixed amplitude you use for the 10kHz tone is such that it is clearly audible to the ear. The 100Hz tone at the same amplitude probably couldnt be heard by the naked ear.

And consequently what we perceive as an equal volume means the low Hz tones are higher in energy.

Anyone got any better ideas?
