Question:
Suppose 2.25*10{eq}^{-2}W/m^2 {/eq} ultrasound is being used in medical diagnostics.
Find the sound intensity level, in decibels, of the ultrasound
Intensity
Intensity gives us a measure of how much of something there is. We often use this to describe the loudness of a sound. Commonly we refer to the intensity of sounds in decibels, which is a reference to how loud they are compared to the lowest sounds we can hear.
