if you're interested in laying down around $200 for some pro earplugs then marshall chasin is the guy to see here in toronto. you can find him here: http://www.hearnet.com/affiliates/view.php?type=1
am assuming on that site you can find somebody close to you. or he would probably know someone.
he does the custom molds to your ears and then makes plugs that reduce noise 15 or 25 decibels evenly. i don't play loud music for the most part these days but these puppies saved my life when i was playing the rock music for the kids. and when laying out that kind of bread you learn how not to lose them!
