Overexposure to loud volumes has a cumulative effect that damages the ears on a physical level. It's not easy to tell if headphones are too loud, and in contrast to speakers, even the cheapest headphone can usually play extremely loud, even with modest equipment. The simplest way to set the volume on headphones at a safe level is to slowly turn them down until it's obviously too quiet, then turn it back up a notch or two. In-ear monitors are noteworthy in that they require an extra degree of maintenance not needed by larger headphones.
The National Institute for Occupational Safety and Health (NIOSH) establishes guidelines for how long we can tolerate noise, and at what levels, before putting ourselves at risk. I figured I would chime in and add that a running lawnmower is about 90dB while a rock concert can be 115dB + which is why it is so important to wear some sort of hearing protection.  Sure it is fun while you are young, but too many concerts and you get to look forward to hearing aids or even deafness. The folks I run into with the most hearing damage are usually from the military who continue to go to the shooting range and not wear hearing protection. When I see this picture, I don't think about hearing damage, instead, I am thinking that perhaps Tyll is trying to tell us that the HD800s sounds like crap. Speaking of unwanted guest; the absolute best way to deal with it, should you ever get it, is to accept it. Turn up cheap in-ears to 110 dB SPL and sound will still be reproduced fairly distortion-free. When I look at a table like your "Recommended Noise Exposure Limits" above, my feeling is, okay, good to know that at 85 dB I can listen for 8 hours, and at 91 dB I can listen for 2 hours.
Without a practical method to measure how loudly I'm listening, that table isn't really all that useful. If there is, mentioning it probably wouldn't use up too many words, and it could be very helpful.
I've heard of folks putting the Radio Shack sound pressure level meter mike through a piece of cardboard and then putting the cans up against the cardboard.
I listen to music at work most of the day at a fairly consistent volume, as others probably do, so it's great to know what the potential impact is. From what I have read so far, it seems the iphone with the correct spl app is fairly accurate within some decibels compared to actual spl meters. Initially I was quite pleased with myself thinking that my extened listening levels were quite acceptable.  But that may be completely wrong and I'm heading out today to find a proper SPL calibrated device at Radio Shack. After graduating from Miami University with her masters in Audiology and doctorate of Audiology from the University of Florida, Krista has been a clinical audiologist with the Audiology Department at the Dayton Children’s for the last 7 years. We have created this blog as a way to communicate key childrens' health and safety issues to parents and other child advocates.

Race fans and gun enthusiasts, for example, require protection to avoid long-term hearing damage.
Hearing a temporary ringing sound after attending a loud concert is a just small glimpse of what could eventually become a permanent condition called "tinnitus". Combine this with the delayed symptoms of hearing damage and it's easy to see why headphone users are a particularly high risk demographic.
Since their tips insert into the ear canal itself, they require cleaning on a regular basis. Most people get yearly eye exams and dental checkups, but surprisingly few bother to test their hearing on a regular basis.
Higher volumes equal shorter allowable exposure time, but it can also be dangerous to play moderate levels for lengthy periods. As can be seen most headphones need very little power to reach dangerous levels especially with today's dynamically compressed music. There is some literature showing how somatosensory inputs from the upper cervical region feed into the auditory system at the dorsal cochlear nucles in the brainstem. But the noise itself is then generated by the brain itself, in a an unproductive compensating mechanism.
But so many are affected, I think it costs the US veteran system billions since so many come back from war zones with the unwanted guest in their head.
So often you are told "everything is in order" when the party only goes to shit when you go beyond 10khz.
Also, I think it's important to test stuff at levels that push them a bit to see if they remain well behaved near the operating limits. When you turn up a cheap stereo you will hear a crazy increase in distortion, and bass output will be limited. For someone who wants to be careful about their hearing, I'd like to understand what the next step is beyond "slowly turn them down until it's obviously too quiet, then turn it back up a notch or two." Is there something I can buy at Radio Shack to measure the volume?
It's been something in the back of my mind and as an audiophile I'm always concerned about potential hearing damage. While still not a professional device - certainly better than any 'App' by a wide margin.  You might balk at the expense vs a free App. Neither the service provider nor the domain owner maintain any relationship with the advertisers. While some types of sensory hair cells inside the ear do have the ability to recover from over-exposure to loud sounds, new research (Kujawa and Liberman, 2009) suggests irreversible damage takes place in other parts of the auditory system. If you value your hearing and plan on enjoying this hobby for many years to come, you'll definitely want to be responsible when it comes to volume levels.

Here's an encouraging note: At volume levels above 90dBspl, the small bones of your middle ear begin to automatically tense to limit damage to the inner ear (called the stapedius reflex).
Sealed headphones, and particularly noise-cancelling models, should require lower levels to get the same music signal to environmental noise ratio. The test produces a chart called an audiogram that looks something like a frequency response chart. Hopefully one day we'll be able to fix hearing damage, but until then, sensible listening habits can't be overstressed.
But with the decreased activity coming from the auditory nerve and ear, the dorsal cochlear nucleus tries to compensate by reducing inhibition, like upping its gain and this somehow also amplifies the somatic information flow, which is abnormal anyway due to my snapped neck stuff. As xnor indicated, musical peaks at even moderate levels might occasionally hit 100dB, so it's not an unrealistic level.
Headphones are weird in that they can totally trick you more than speakers into listening too loud. In case of trademark issues please contact the domain owner directly (contact information can be found in whois). In-ear monitors tend to isolate fairly well but are also very sensitive and thus easier to accidentally play at extreme levels.
It's a relatively simple process that can be done by an Audiologist or most hearing aid dispensers. I'm certain I know what 110-115db sounds like (I don't go there very often, or for long) and I found all the apps I tested fell short by around 20db. Years down the road, when the hearing problems actually do surface, there's no way to go back and reverse the process. Yes, your music will actually have better sound quality if the volume remains at a moderate level.
A good practice is to completely lower volume on the playback device before inserting the monitors, then slowly raise the volume to comfortable levels. Routine testing makes it easier to spot early signs of hearing loss and make the necessary adjustments to help combat further damage. Larger chains like Costco sometimes offer free testing but it's definitely worth paying for if needed.
