Decibel limit

The first paragraph actually describes how the first paragraph describes the situation. That's a nice iteration, although things like this can be dangerous in their own right. To computers, that is.

You quite possibly upped the Region gain by 30dB. That's about 32times as loud. That's pretty loud. Now you know.

Your question is a bit like 'I bought a Ferrari. But sometimes, if I push some levers, I don't remember exactly which ones, it gets quite fast. I mean, really fast. Dangerously fast. Isn't there a switch somewhere that prevents this ? And flicks on a light that says something like "Dude, you were about to kill yourself. Try to avoid this." ?'

Frankly, if you're listening so loud that a full scale sound would break your headphones, you're doing something wrong. Turn down your headphones, if just for your own hearing.

Your Mac's system preferences provide little means to prevent you from doing, um, unclever things.

As far as Logic goes, you might be able to rig something up in the stereo out, but how on earth would you be able then to generate a mix with a healthy level ?

if you're able to isolate the source of the noise, then a limiter on your physical outputs would do the trick in some cases. at that stage, the sustained amplitude would be the limiter's peak +12 dB (if my memory serves me correctly). just remember to disable them during bounce.

Are you talking about an unexpected blast of white noise? Or was it your music, but it just got really really loud?
