Frequency/Period

Sound is a periodic event. This means that there is a fixed amount of time between different events.The Frequency component of a sound wave affects the pitch of the sound.

Frequency if the measure of how many cycles a wave complete per second.

Frequency (f) is measures in Hertz

Period (T) in the inverse of infrequency is is measured in seconds

Frequency = Cycles/Second Period = Seconds/Cycle

f = 1/T T = 1/f

Different types of frequency components periodic / aperiodic. Periodic sound that has a measurable frequency

Aperiodic sound that is mostly random

It is assumed the humans can hear frequencies from 20Hz to 20,000 Hz.
