Question

definkey word and what ispitchand sherillness

Answer 1

The pitch or shrillness of sound is determined by the frequency of the sound waves detected by the ear. The higher the frequency is, the higher the pitch will be. Pitch corresponds directly to a repeated event per time.A sound wave, like any other wave, is introduced into a medium by a vibrating object. The vibrating object is the source of the disturbance that moves through the medium.
