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.
