A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave. A high pitch (>2kHz) will be perceived to be gettin ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
