Here's a table with examples of sound pressure levels in Pascels and decibels. There, the level for hearing damage for long term exposure is ~85 dB and for short term exposure, it's ~120 dB. The threshold of pain is ~130 dB. Be glad that they don't test you at ~191 dB. For usual atmospheric pressures, that's when the rarefaction part of the sound wave approaches a vacuum, so the sound intensity can increase only in the compression part beyond that. Then it's called a shock wave.
