Probably bad for your hearing too

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
But would they, technically speaking, be scared?
Maybe? How fast does being scared process? Because if they die faster, then they won’t be scared.
