Sound Intensity:
Pressure (p) is defined as the Force (F) per unit Area (A).
- So, the larger the Amplitude (or Pressure Difference), the louder the sound you perceive.
- Remember: The rate of energy transfer is called Power, measured in Watts (W).
Human Perceptions of Sound Intensity:
How good is your hearing?
