본문내용
1. Amplitude, Power, and Intensity: indicators of the strength of sound
1) Amplitude [★★]
- difference between average value and maximum value of acoustic variable
= maximum cyclical change in quantity
2) Power (P)
- The rate of energy transfer or the rate at which work is performed [mW,W]
- Determined by - sound source - rate of decrease depends on wave and medium
- Operator adjustable - Relationships: Power is directly related to amplitude
