Loudness and Pitch of Sound

10.2  Loudness and Pitch of Sound
   
  • The loudness of sound produced depends on the amplitude of the sound wave
  • Pitch of sound depends on the frequency of the sound produced
  • Frequency is measured in the unit of hertz (Hz)

The relationship between loudness and amplitude

  • When wave amplitude increases, louder sound is produced

The relationship between pitch of a sound and frequency

  • When wave frequency increases, higher pitch is produced

Doppler Effect

  • The Doppler effect is the apparent change in frequency caused by the relative movement of sound source, the relative movement of the observer or both.
