1 answer

The three parts of sound typically include:

  1. The energy source - This is what produces the sound waves (e.g., a vibrating string, vocal cords, etc.).
  2. The transfer of energy through a medium - Sound requires a medium (like air, water, or solids) to travel.
  3. The detection of sound - This refers to how sound is received by our ears or other devices.

The identification of pitch is related to the perception of sound but is not considered a fundamental part of sound itself. Therefore, the correct selections are:

  • The energy source
  • The transfer of energy through a medium
  • The detection of sound
