Well, just pointing out that foam ear plugs aren't advisable on take off or landing unless you make sure to equalise, as you do. Someone who doesn't know that might think they are safe all the time without doing anything.
I measured the upper deck of an airbus and it was in the 60's. If my memory is correct I believe the average was around 68dB. It was the quietest airplane cabin I've ever been in.
Just an update : I ended up flying with a Boeing 777 wide body and I measured it to be around 85 dB the whole time but I was still pretty ok with ear muffs. Didn't sleep through take off and landing but I did sleep for the whole flight otherwise. I don't have any increase in my T.

That's pretty loud for a plane cabin. What did you use to measure that? I have measured various cabins on different planes and would say the average is around 79dB. That's excluding take off of course.
But it also depends where you sit. I always booked seats as far forward as possible. I can imagine some seats could potentially hit 85dB.
A continuous level of 85dB would surely suggest that all flight staff should be wearing hearing protection though? In accordance with occupational health.
