Do I hurt my ears at listening to music at and around 70 decibels?

I can sometimes turn it up to 75 decibels (according to a decibel meter app on my phone from my listening position).

I usually listen at around 65 decibels. And on my iPhone through my Marshall major 3 I rarely go over the halfway mark.

I estimate my listening time a day to be 3-6 hours excluding YouTube watching.

I’m 18 years old and gave a slight ringing in my ears and I am a little bit scared of my hearing getting worse.
