Maximum 80 db. Plenty loud enough and does not worsen my tinnitus.
Same boat...
Maybe 85 dB peaks, average 70dB.
I recently compared dB Pro and NIOSH SLM (free) and they are virtually the same.
I designed my system to protect my already damaged ears.
As I write this I’m listening to TP Echo 65dB avg / 85dB peaks and it fills my large room with satisfying sound - and at 10ft from the speakers is more then enough to feel the music.
@moonwatcher tinnitus is the brain’s perception of / compensation for hearing loss - it can’t really change with stress but the perception can be affected by blood pressure and other things (alcohol, coffee etc.) - it also cannot be measured, your actual hearing loss can be quantified, of course.
