    So...

    When you reach a certain dB (SPL) level, you are at a point where the air (the medium here) cannot be rarefied anymore, but you can keep compressing it.

    Does this mean that when you pass a certain point, the sound waves on a 'scope would keep compressing, but on the bottom it would go to a certain point, then flat-line before returning back to the reference point?

    What I'm more interested in would be what happens once you reach the maximum rarefication point. Since you're trying to rarefy it even more after that point, would the pressure start rising early and cause the bottom part of the wave to have a distorted shape, or what?

    You could always just increase the air pressure to allow more rarefication, but that would make what I'm asking pointless.

    Thanks.

    Now you are into the field of nonlinear acoustics.
