Sound is described in terms of two characteristics:
Frequency (or pitch) is a measure of how many vibrations occur in one second. This is measured in Hertz (abbreviation Hz) and directly corresponds to the pitch of a sound. The more frequent vibration20 Hz to 20,000 Hz (20 kHz) Sounds below 20 Hz are infrasonic, Sounds above 20 kHz are ultrasonic. occurs the higher the pitch of the sound. Optimally, people can hear from
Amplitude (or loudness) is the maximum displacement of a wave from an equilibrium position. The louder a sound, the more energy it has. This means loud sounds have large amplitude. The amplitude relates to how loud a sound is.
