## Homework Statement

A jackhammer with a sound power of 10 W is operating in the countryside. Calculate the

intensity levels at distances of 2.0 m and 50.0 m from the jackhammer. Calculate the

corresponding levels in dB.

## Homework Equations

β = (10dB) log (I/Io)

where, β = sound intensity level, I = intensity, Io= 1.0x10^-12 W/m^2

## The Attempt at a Solution

I honestly have no idea how to do this question! Please help
