136 Db?!! That's really high SPL's I'm amazed you can still hear. I've read 122Db on stage once playing guitar. I recall bending over to pick up a tangled cable and the pressures from a bass amp make ya' dizzy for a few seconds. Problem is you build up a tolerance for high Db's and don't feel it's way too loud when it actually is! Listening to headphones is another culprit especially in recording studios for hours.
