I find surprising how little attention it got when I posted it (still very few views), but I see it is a frequently asked question here

This is huge, if true.
Perhaps the bassheads will have the last laugh -- keeping their hearing longer than the more well-rounded audiophiles who often act as if the bassheads are a lower form of music listener.

Be careful, the hair cells for the low frequencies are deeper in your ear, and you expose the ones for higher frequencies also to the low frequencies. AFAIK, you can damage the hair cells for higher frequencies with low frequency SPL even without noticing (precisely because our ear is less sensitive to low freq.).

For example, scientifically speaking, I might be able to see how 100db (pick a number) coming into your ears from ear canals over time might have a different effect than 100db coming from a speaker system, even if its in a car, etc.
Something to do with 1 of these 2 experiments, your eardrums have more airspace, etc., to deal with, and borrowing from material fatigue experiments, etc --> long story short is I wouldn't be shocked if it turns out that 100db x 1000 hours from IEMS is more damaging to hearing or ears than 100db x 1000 hours from speaker system.
I'm not sayin the above is true. But I will say this, as a gut feeling: if I had to choose between being exposed 1 hour to 140db via IEMS vs. 1 hour 140db via speakers, I'd choose the speakers...just seems to make sense that the speaker experiment *might* be less damaging --
the human body might be naturally more resilient to loud db's coming from far away, vs the more unnatural piped in dbs coming from iems.
I suppose counterargument is the above is irrelevant - whats important is the db level when it hits your eardrum...

You might be right here, but I am unsure. I actually find strange that my sister's audiologist told her not to use headphones at all for listening to music (she has a partial hearing loss). I would really like to discuss this matter with him, but I doubt I will get the chance (my hearing is good). And I am unsure because with the speakers, you get SPL everywhere in your body, including your mouth. Opening your mouth alleviates the pressure on the ear.
