Question:

At a distance of 15 m from a sound source, the intensity level is 60 dB. What is the intensity level (in dB) at a point of 2.0 m from the source? Assume that the source radiates equally in all directions.

Sound intensity level

Given the sound intensity {eq}I {/eq}, the sound intensity level {eq}\beta {/eq} is

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

where {eq}I_0 = 10^{-12} \ \text{W}/\text{m}^2 {/eq}.
