I just saw the video on the Tinnitus Hub

I feel bad for him and wish him a quick recovery. But hopefully that will raise awareness. People
should all know that one should not stand next to such ridiculously loud noises.
A quite similar story (and by this I mean, a "celebrity" subject to loud noise accidents) happened to the goalkeeper of the Lyon football team a few months ago.
Some savages from the terraces sent big firecrackers next to him and he suffered a trauma.
Video here for the curious ones:

Fortunately he then fully recovered from it apparently.
