Hearing damage occurs at 130 db in a matter of moments. But hearing damage STARTS at about 85 decibels (that's about the volume of a kitchen blender).
Those who want to say that is wrong should research the topic thoroughly before vouching an opinion. (I suggest Wickipedia; they are easy to search).
A loud volume for a short time, or a medium volume for a long time will both cause permanent damage.
Now as to how to avoid hearing damage?
I've been to places where the music is so loud that - even with ear plugs - the volume is still above the hearing damage threshold.
If my ears are ringing when I leave a place - even with ear plugs - then I NEVER go back. That place can do without my money.
I will not damage my ears just because everyone else does. Nor should you.
Anyone who spends their time around hearing damage volumes and thinks they have no hearing damage is kidding themselves. They, literally, do not know what sounds they are missing. The loss is so gradual that they don't notice, that's all.
I've protected my ears, and also avoided loud music over the years. And I'm seeing my friends losing their hearing bit by bit, until they've gotten to the stage where they say "What?" a real lot during conversations. Or they reply to the wrong thing (which they thought you said, because they missed hearing a word or two correctly).

Some folks think loud music is cool.
But - How cool is it to talk to someone with whom you have to constantly repeat yourself over and over, because they can't hear you? It's annoying talking to people like that!
.
So they question was - "How do I sing and still protect my ears?"
1) Avoid hearing damage volumes at all costs.
2) There IS no #2, my friend! . . . unless you can learn to sing with earplugs or headphones on.

Sorry.
You have no choice: You will need to be in a group doing music that will not hurt your hearing.
So, you have a MAJOR decision to make.
Because if you want to avoid hearing damage, then you must NOT be around hearing damage volume levels.
Period.
