So he's low 7B with prep time and the 300 decibel soundwave emitters. According to this page: http://www.decibelcar.com/menugeneric/87.html
It states the following just to give an idea:
248dB Atomic bombs dropped on Hiroshima and Nagasaki, Japan, August 6th & 9th, 1945. Total disintegration of 16 square miles, wind was around 300 miles per hour, destroyed 28" thick concrete walls at 1 mile distance. Leaving a crater 633 feet wide and 80 feet deep.
286dB Mt. Saint Helens volcanic eruption
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.
I'm not a big physics person so if I'm wrong then just lock the thread.
