For reference, the loudest sound ever on earth was 180dB https://wikipedia.org/wiki/1883_eruption_of_Krakatoa

The decibel scale is logarithmic, meaning that a 20,000 dB sound would carry an unimaginable amount of energy.

A hypothetical 20,000 dB sound would have an overpressure of approximately 5 x 10^499 atmospheres, enough energy to obliterate the Earth instantly.

    And definitely scare off the tigers

    Oh yeah, those tigers would not be hanging around

    You won't hear it coming

    Amazingly, given the relatively slow speed of sound, you might actually see it coming. For a moment or two at least, before you're vaporized or whatever.

    Hmm. It wouldn't stay sound for long. The molecules would be banging together so hard that you'd get all sorts of interesting nuclear reactions. I'm not guessing how that turns out. But, for sure, you'd get a lot of EM radiation coming at you at the speed of light.

    ETA: Come to think of it. You'd also get unknown gravitational phenomena, also travelling at the speed of light. Presumably. The data would be invaluable for unifying relativity and quantum physics. Definitely dead before you know, though.

    Yeah, I was just thinking of like an extremely powerful soundwave, but I guess I just can't really imagine what a blast of that magnitude would look/behave like.

    No worries. No one can. Everything we can observe is perfectly explained either by relativity or quantum physics, but never both. They are incompatible theories, which are applied in different conditions. In such extreme conditions, both would apply. IE, we don't have a theory for it.

    Since we cannot create anything remotely close to such conditions, like a black hole, we do not have the data to create such a theory. Just like AI, we are limited by our training data.
