Homework Help: Physics of Sound & Music NEED HELP!

  1. Jan 24, 2008 #1
    Does anyone know how to solve this question?

    The atmospheric pressure is 0.850 atm. The rarefactions of a particular sound wave then reduce the pressure to 0.841 atm, what is the amplitude of the pressure wave expressed in metric units N/m2(squared)?

    Welcome to PF forums!! If you've looked around, I believe you will find some very useful and interesting discussions as well as helpful people. Before we can give you some guidance, you will need to show us some work. What is your thought process so far, and attempt at a solution? (please reread the sticky thread at the top of the forum page). You might start by defining some terms. What does rarefaction mean in your example?
