Introduction to Signal Levels

Sounds travels as a wave. The amplitude of the wave is related to the amount of acoustic energy it carries, or how loud the sound will appear to be. As the amplitude of the sound wave increases, the sound is perceived to be louder. There are several different ways to describe the amplitude of a [...]
