Loudest Sound Ever?

@millercarbon But what about Supertramp "loud".  Must be near the envelope to crush matter into a singularity, yes?  And, as an aside, I particularly like the Hawking theory that black holes evaporate!  Wowzers that some critical listening/thinking.  No snark.

Black holes may burp, perhaps that is what was heard….

As I have gotten older, I have less tolerance for very loud music.  At a rock concert, I have been known to pack my ears with cotton so that I can enjoy the music without grimacing in pain.  At home, my listening level is low-to-medium — definitely lower than probably a lot of other members here.  Only occasionally will I listen at louder levels, and usually that is when driving in my car. 

Black holes do not burp. You are maybe thinking of Hawking radiation?
