Question
If the rarefactions of a particular sound wave reduce thepressure to 0.997 atm, what is the pressure in the compressions?What is the amplitude of the wave, expressed first in atm and thenN/m2? Is this a soft or a loud sound? I know that the pressure exerted by the air under normalconditions is 105 N/m2. But how can I usethis information to determine the amplitude of the wave.

But how can I usethis information to determine the amplitude of the wave.Explanation / Answer
Since in normal conditions, the air pressure is 1 atm. And therarefactions of it reduce the pressure to 0.997atm So the pm = 0.003 atm. We have the equation: pm=vDws (s is the amplitude ofwave)
