the crest-factor decribes the energy of the sound in relation to its
amplitude. the waveform with the highest crest-factor is a squarewave
(imagine: the positon of the membrane of the loudspeaker is always at
maximum position). using a square should result in the maximum loudness
at a specific amplitude.
our is ear is the most sensitive in the area between 1 to 4kHz (as chris
and derek already mentioned).
what about making the beep-sound of your buzzer pulse? noises without
constant amplitudes seem to get more attention.
