Are your listening levels healthy? Doing damage?

My experience with a few Android SPL meter apps was that they were garbage. Not accurate at all. Buy a "real" calibrated SPL meter from a reputable brand and call it a day. It should last you a lifetime as long as you don’t leave batteries in it more than a year at a time (leaking batteries is sadly still a thing here in 2023).

I listen in the 80 to 85dB range most of the time, occasionally "rocking out" once in a blue moon to the low 90s. At night, I listen to music in the mid-70s range to wind down and go to sleep. I learned my lesson. And too many loud concerts have taken their toil over the years, along with ironically my various car systems over the years. I really did more damage with my car systems than I ever did with my "real" stereos. I have 8000Hz tinnitus now that varies from being ignorable to being pretty loud depending on my stress level. I wouldn’t wish tinnitus on the Devil. It is definitely no fun and distracts from the pleasure of listening to music.

Maximum 80 db. Plenty loud enough and does not worsen my tinnitus.

If you need to turn it up loud to sound good, then your system needs work.

 

I have some damage from when I was young and couldn’t afford a good system.

Agreed.

I have some damage from guitar amps and at 67, have no desire to incur any further damage. 75 db peaks is my top limit. Most of the time it's more like 70db.

I typically listen at 65 to 70db with peaks to 75db. 
 

The caution is that over 85db for eight or more hours can cause hearing damage, 88db for 4 hours, 91 db for 2 hours. 70 db or under is OK for as long as you want. 
 

So, unless you are into headbanging volumes you are probably good.

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.
