A speaker so loud it can kill you

Yeah just don't drive with loud music if you are black and live (if you call that living ) in Florida..

My speakers are so loud they could get me killed! By the neighbor!

Here, here.

Nonoise's story brought back to me my experience back in 1978 or so, when Deep Purple cracked the ceiling of the Norfolk Scope, an all poured concrete structure. It was so loud I made earplugs out of wads of toilet paper, I was only 16, so that says something. 135db according to what I read about it afterwards, they and Kiss and others were in a competition to be the loudest band in the world, but a few instances like that created a law that no concert is to be over 110db in America. But 110db is still Very loud! And who is really policing that law anyway?

Loudest ever was the giant steel and concrete horn used by NASA to (I guess) simulate what effects the sound of a huge rocket (like the Saturn V) would have on the surrounding area.

It was made at the Marshall Space Flight Center in Huntsville, AL.

The max output SPL was a lethal 210 decibels.

From the Guiness Book of Records:

"The loudest noise created in a laboratory is 210 db or 400,000 acoustic watts reported by NASA from a 48 ft steel and concrete horn at Huntsville, Alabama in October 1965."
