WebSection Summary. The energy carried by any wave is proportional to its amplitude squared. For electromagnetic waves, this means intensity can be expressed as Iave=c0E202 I ave = c 0 E 0 2 2 , where I ave is the average intensity in W/m 2, and E 0 is the maximum electric field strength of a continuous sinusoidal wave. WebSound intensity (or sound pressure) is measured in decibels (dB). To better show how humans perceive sound intensity, the decibel scale is logarithmic. The dB scale shows sound intensity, and the dBA scale shows sound intensity depending on the response of the human ear. For this reason, the dBA scale is typically used to describe sound level ...
