Question
If a sound intensity level of 0 dB at 1000 Hz corresponds to a maximum gauge pressure (sound amplitude) of $10^{-9} \textrm{ atm}$, what is the maximum gauge pressure in a 60-dB sound? What is the maximum gauge pressure in a 120-dB sound?
1. $10^{-6} \textrm{ atm}$
2. $10^{-3} \textrm{ atm}$
