In the EDM scene few DJs and Producers what i've seen and heard, actively promote to wear ear protection at their shows or them self being role models and use some. Approx. 1 year since i was at a EDM show last but i really hope it has change some way.
I know in Sweden anyway a large amount of musicians, producers went out in a joint debate article in newspapers for few years back telling about their way in a down spiral to being T sufferers but still working with music and wanted visitors to their shows using protective ear plugs.
