### Sound level ${L}_{P}$ in units of decibles (dB)is determined by:${L}_{P}=20{\mathrm{log}}_{10}\left(\frac{P}{{P}_{0}}\right)$where p is the sound pressure of the sound, and ${p}_{0}=20\ast {10}^{-6}Pa$ is a reference sound pressure (the sound pressure when ${L}_{P}=0dB$). Determine the sound pressure of 90 dB noise (noisegenerated by a passing truck). By how many times the soundpressure of the truck is larger (louder) than the sound pressureduring normal conversation where the loudness is 65 dB?
