This cuts across production to reproduction, whats the middle ground? Whats your take on these issues?

Several reasons why you, your customer and your DJ are probably deaf

2. Permissible Exposure Time for Noise SPL sound pressure level and duration Guidelines How long can a person endure a certain noise level before hearing damage occurs health sound level noise hearing ears impairment tinnitus damage - sengpielaudio Seng
Note if your studio engineer mixes at the SPL levels in clubs, hes also likely deaf, if he mixes lower than 60dB SPL, then playing back the mix at levels lower than 60dB SPL, will have no issues with Fletcher Munson curves

So in the end its probably all good😉
 
I suspect my current job in a kitchen has (perhaps seriously) affected my hearing. Sometimes someone will bang an implement (spatula, etc) on the grill, really hard. Loud enough to make my ears ring instantly. My left ear (usually nearest the grill in question) often has ringing at around 6kHz or so, which I noticed started after a particularly loud bang.
The chap doing it is a drummer in a metal band, so he hits hard and is pretty deaf himself.

At events, its as loud as it needs to be. If the drummer is absolutely destroying the kit, its my job to ensure the sound is still balanced. I've had 115dB 5m back for a 45 minute set before now. Earplugs went in very quickly.
DJs will always insist that the system is run flat-out. I usually make sure the bass is felt for the first 1/3rd or so of the audience, and call it good.
