Loudest Sound Ever?

Bassnectar show at Red Rocks 2017.. peaks at 110 dbs.. Made Red Rocks change their rules on volume and Bassnectar was banned for life.. 

Second loudest: 10 Billion Butterfly Sneezes...

P-51 race plane!

Me. After reading the prices of high end gear…

In '69 I worked the summer for Marriott Corp, on one of those trucks that rises up to the plane to swap out food service stuff. We spent 1/2 the time just sitting near the runway, waiting for the plane. We weren't issued ear protectors so really got a close up experience of jet noise.

The 2 loudest were the Boeing 707s (various configs had been in use for years by then); and the then-brand new 747. The 707s had sharper, more painful sound (extremely loud engines) and the 747s had deeper, more menancing bass sound (bigger planes & engines).

Many times we sat in that truck buffeted by sound that felt like a storm (the truck shook like it was). No doubt helps explain my constant tinnitus...
