This article appeared in the NYT yesterday:
https://www.nytimes.com/2022/08/16/well/live/headphones-hearing-loss.html#commentsContainer
It irked me that the author and the docs she interviewed talk about decibels. Turns out the CDC article linked in the NYT article doesn't get it right, either. The NIOSH article linked by CDC does.
https://www.cdc.gov/nceh/hearing_loss/what_noises_cause_hearing_loss.html
It also contains gibberish: The time estimates listed in the “Typical Response” column are based on the NIOSH exchange rate of 3 dB. Huh?
The 80 for 90 rule that the first doc in the NYT article refers to is also cute in that it implicitly assumes that volume sliders, output voltage and headphone sensitivity are standardized. And we haven't even talked about output and headphone impedance.
Confirms my prejudice that most MDs know just enough about science and tech to be dangerous.

Charles, don't you get me started!
I have had audiograms taken for myself or my kids at various ENT specialists. Usually, the cabin was not all that well insulated. Used to be that they also had a CRT monitor emitted some 15 kHz noise but those have gone the way of the dodo. How are you suppose to measure thresholds under those circumstances? Then, the earpieces are usually slightly concave dishes made from hard plastic. The distance to the ear canal is unfined as are possible resonance in the space defined by eardrum, ear canal, ears, dish and random leaky seal. Or is the leaky seal supposed to yield low Q resonances?
And I haven't even started bitching about internal medicine...

I much respect Medicine, the mainstream one, but have been in close interaction with Doctors from Day 1 , literally, born and raised in Hospitals where my Father practised and had living quarters as a Resident Doctor, go figure, plus having Brother and Sister studying Medicine, I passed the Admission exam my self (it was some kind of Family challenge), running his Hospital as an Administrator for years until we sold it, yet fully recognize Medicine is not truly a "Science" 😱 (in the way Physics, Chemistry, are) but very empirical.
Not bad by itself but 99% of Doctors have no clue about Statistics and are quite prone to have pet theories based on "samples of 1" or not many more, statistically irrelevant.
That´s why so many completely clashing theories abound about anything in that field.
