Incorrect. Find the intensity of noise for a whisper and a normal conversation:
$\displaystyle{30}={10}{\log{{\left(\frac{{w}}{{P}_{{0}}}\right)}}}\usepackage{cmbright}\Huge\$ and $\displaystyle{64}={10}{\log{{\left(\frac{{c}}{{P}_{{0}}}\right)}}}\usepackage{cmbright}\Huge\$

Divide both equations by 10, rewrite as exponential equations, and multiply both sides by $\displaystyle{P}_{{0}}\usepackage{cmbright}\Huge\$ . Divide c by w to compare the two noises. Use the laws of exponents to simplify the quotient and evaluate, using a calculator.
