I’d just like to add-
 I regularly used to work most days of the week, for extended periods, at levels that were averaging 115 to 131 dB (A weighted) which is wholly illegal in most parts of the world where The Worlds Loudest Band (Tm) who I worked for regularly played.
We would wear our in-ear monitors (with built in -33dB reduction) underneath -30 dB shooting cans over the top of them. Yay….
 All it took was five seconds of 115dB from a 15 watt Vox ac15 guitar amp, right in my right ear from 1 metre away without protection because I was tracking down a hum and that’s my enjoyment of stereo gone for life. It has not recovered, and almost every second of every day is now accompanied by wierd howling, ringing, humming noises (tinnitus). I can’t hear most conversations held with normal people at normal volumes…
 Once, about 2 years ago my damaged ear popped for a second and I got about 30 seconds of pure, unadulterated binaural hearing back and it was so amazing it made me cry.
Hearing loss is not a joke, and at high Sound Pressure Levels, it is an ever present danger. It only takes a few seconds, and that’s it gone. Haha no oops bugger….

I’ll be wearing ear plugs under my helmet, and fitting a boring levels silencer to my Riley, no matter what it does to performance..Them’s my reasons, and I’m sticking to em…
