Random crab I read today...
1100dB would destroy the universe
310dB Krakatau volcanic eruption 1883. Cracked one foot thick concrete at 300 miles, created a 3000 foot tidal wave, and heard 3100 miles away, sound pressure caused barometers to fluctuate wildly at 100 miles indicating levels of 190db at that distance from blast site. Rocks thrown to a height of 34 miles. It was still less then 1% loud enough to destroy the universe at 1100DB's
