loud for me is all the amp has but it is driving low efficiency speakers so maybe 100dB and a little more. Normal is well below that. Unless I'm engaged in serious listening, I'm probably somewhere in the 70s. I use earplugs anytime I'm using loud tools, lawnmowers, blowers and such or as needed professionally. Let me add this...most will listen at different volumes, depending so I've put in normal and loud levels. Let's see both if you know them.
