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 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.

To determine the intensity level in decibels, we would use the equation

{eq}dB = 10log(\dfrac{I}{I_0}) {/eq}

where {eq}I {/eq} is a given...
