There was this posted in its own thread recently as well:
The article seems to suggest a couple of relevant possibilities. One is that damage to hearing takes place more often than we realise, but is hidden because "natural plasticity can compensate for inner ear damage to bring sound detection abilities back within normal limits." This would seem to reinforce the idea that the guidelines about what is safe might possibly be misleading, at least for some people, because much hearing loss goes undetected.
The article also seems to go some way to explaining why those with significant damage perceive some sounds as being louder than do other people with less damage:
""Like feedback from a microphone, having too much gain in the system can push neural circuits toward becoming pathologically hyperactive and hypersensitive," said Dr. Polley. "By establishing the actual cellular components of the brain's amplifier, we hope that one day we might be able to turn the volume knob up and down to find that 'sweet spot' where people can reconnect to the auditory world without hearing phantom ringing or cringing at a loud noise that most people would shrug off as 'tolerable.'"
Not quite sure how this helps @LeQuack. My take away from it is that little is known with certainty about what is absolutely safe for hearing. 'Everyday' sounds might be damaging for our ears or they might just be producing temporary but unpleasant increases in our symptoms. I'd guess that both are true in different situations and with individual differences in biology and/or possibly levels of previous damage.
One thing I would say is that although addressing psychological issues like anxiety or depression might be helpful in itself because of the suffering they can cause, it probably isn't helpful to assume that if somebody suffers because of exposure to 'everyday' sounds then this must be caused by some psychological issue.
Clinical evidence of the "gain" being turned up in the cortex to compensate for reduced hearing input.
