Can you clip a soundwave?

    Not the signal that is producing the soundwave, but the soundwave itself.

    A soundwave consists of alternating compressions and rarefactions. We can compress air to several thousand PSIG (at least)
    which would give a pretty high limit for the positive part of the cycle. But we can only produce rarefactions down to 0 PSIA
    (about -15 PSIG) for the negative part. So I would imagine that with a high enough level, we would hit the negative limit at least,
    and start clipping.

    I am wondering if real life sound levels are even anywhere close to this limit? Or if it has ever actually occured?

    Atmospheric pressure is about 100k pascals, and 0 dB SPL is 20 micro pascals. So, the "clipping" limit would be around 440 dB SPL.

    That would be loud.

    All that's needed is to direct opposing compressions and rarefactions into each other, in a manner that creates disruptions in the waves, turning the "inchworm" expansions and contractions into a series of - - - - -.

    OKay, I'll ask the question on everyone's lips: Why would you want to? (Actually, I am kinda curious).
