CHARACTERISTICS of sound waves?

Answer 1

Sound waves are defined by the following characteristics:
Amplitude(Amplitude): it's the maximum value that signal can reach.
Periode (T): It's the time took by the signal to complete a cycle.
Frequency (f): It's the number of cycles per second.
f=1/T.

Answer 2

The two main charactoristics would be volume and frequency. Sound waves are really disturbances in air pressure, so the volume or loudness of a sound is really the amount of variation in the air pressure, and the frequency is how often the wave crests follow one another. The frequency is x number of complete waves per socond.

Answer 3

a disturbance in the air, like when a "tree falls in the forest but nobody's there to hear it, does it make a sound?" of course it does because the sound is a disturbance in the air, regardless of if anyones there to listen to it :)

Answer 4

It has a through and an amplitude.
