I can tell when I need to lower the volume of something I'm listening to when I feel a kind of tightening in my ear muscles, and/or ringing in my ears, or a slight feeling of stress coming in from my environment.
I also just try to remember to always proactively lower the volume a couple ticks from what i first set it at, to prevent all those sensations.
What are the signs for you that things are a little too loud?
