I mean, tinnitus can be pretty harsh. Anyway, are people really supposed to get tinnitus? Is that the fault of the nightclub or the customer? Actually, it seems like it isn't the decibels but something to do with the high pitch. For instance, someone might get ringing ears from a small speaker with no bass.
I'll admit I wear hearing protection at times (inner ear and over ear specifically). But then again when I'm firing my rifle (at roughly 160 decibels per shot) it gets kinda loud... well into the instant hearing damage zone. (Plus each shot actually would hurt because it's over the threshold of pain. The pain threshold is 140 decibels.)
I don't like to go to clubs or things like that though. But when it comes to the cause of tinnitus, it has nothing to with the size of the speaker as even a small speaker can get very loud. The pitch is not super important either (a high pitch might sound more annoying) but if the decibel level is the same it's likely going to cause pretty much same level of damage over time.
The main thing to worry about is duration of sound and decibel level. I mean for every 3 decibels over 85db the amount of time it's safe is cut in half (up to 120-125 where it's just never safe without hearing protection). So if the sound is over 110 you only have like 30 seconds before hearing damage can start to accrue. It's not going to happen instantly where you're just deaf, but over time/through constant exposure you'll notice you can't hear certain tones as well, you might need to tell people to speak up more, etc...
So people who wear hearing protection at clubs are probably smart if they spend any amount of time at them.
As for who's fault it is? The club's for having the music that loud.
It depends on whether or not the club purposely turns it up past 120 decibels, and if the person coming in already has issues from other items that are that loud.
If the club plays the music loud enough to potentially damage hearing, then it's their fault; but if someone goes in and doesn't wear protection and gets their hearing damaged, it is that persons' fault for not planning before hand.
I don't think people are wusses for complaining. Some people don't have ear wax I think. I mean, suffering thru music torture just to be macho? Come on now!
But it does seem like at a younger age, there was more ear wax. But I think I did have some pain after loud amplified music, but it wasn't the same.
Oddly enough, this stuff doesn't start to bang your ears until an hour or so after the music.
People who wear hearing protection are not weak they are just trying to protects their ears from being damage due to excessive loud noise in the environment they found themselves. As the popular saying "prevention is better than cure"
