      Even if they are active, they will just cancel out the external sounds. I am not sure how to work it out, but I would expect the energy to transfer to heat or somethin'. I would think that noise cancelling headphones would reduce hearing loss, as you don't need as much sound.

          Nice try, but this doesn't apply to Bose. Their good reputation stems entirely from marketing. In fact, their products are mediocre at best, certainly not 'pretty good'.
          Bose tends to market their products using technobabble that impresses the mainstream consumer, but is absolutely ludicrous to anyone with a modicum of knowledge of acoustics. Their 'surround with 2/3 speakers' claims are a good example: it doesn't bloody work!
          Try comparing Bose products to equipment that costs the same, but is produced without the technobabble influence. Mainstream stuff will do, nothing exotic is necessary. The Bose stuff won't sound better.

          I did this once with a set of Bose 301 speakers versus a set of Magnat Concept 2 speakers (about $100/pair cheaper than the Bose set). The Magnats had a much more linear frequency response, the Bose really emphasized the midrange frequencies too much. The Bose's direct/reflecting system made them sound unfocused: close your eyes and you've no idea where the sound comes from. With a good system, you should be able to point out where the instruments are - can't do this with the Bose, piece of cake with the Magnats.
          Also the Magnats were far less fatiguing to listen to (side effect of the flat frequency response).

            From a soundperson perspective I find this discussion 'A is better than B' a bit pointless. In a discussion "Bose vs Magnat", "Better" is relative.

            First of all recording technique makes a huge difference in this. In signals recorded with crossed microphones (x/y), locating the instrument is a piece of cake, though it might lack in 'spatial' feeling. When recorded with 2 parallel mics (A/B), things might sound very spatial but locating the panorama of the instrument in the stereo image is much harder. For this reason, most pop recordings are recorded in X/Y (mono compatible for radio play, good panning, does not sound very spatial) while most classical/jazz is recorded A/B (spatial sound but poor localization of instruments. Phase problems may occur, possible mono incompatibility).

            Something similar happens in playing back the sound. Bose designed their speakers to have an as large as possible 'sweet spot', resulting in a more consistent spatial sound across the room, however this is at the cost of localization of the instruments.

            The magnats have a relatively narrow 'sweet spot' compared to the bose speakers. As a result, localization of the instruments in a stereo image is more accurate, but the 'sweet spot' is much smaller.

            All other things left out of consideration, if accuracy in stereo image is your thing, you'll prefer the Magnats. If you prefer consistent sound all over the room, you'll prefer Bose.

      Since the headphones actually reduce the amount of sound, the are not damaging your hearing.

      On the other hand, since noise cancelling only works on low to mid frequency noise, and hearing loss is caused by high frequency sound, they aren't helping either.

      On the third hand, if you are using noise cancelling to allow you to listen to music at a lower volume in a noisy environment, then they might actually help out a bit.

      • hearing loss is caused by high frequency sound

        Hearing loss is caused by a number of factors; yes, loud sound can do it, but high_volume != high_frequency. Where did you unearth this particular piece of mis-information??

        According to the the American Speech-Language-Hearing Association [asha.org] there are at least seven causes of hearing loss in adults. PS, "high frequency sound" is not on the list.

        Neither is "marriage", but that's a topic for another time... :-)

          Take a course in biology and you'll learn that high-frequency noises are indeed related to loss of hearing.

          The cochlea (inner ear) uses tiny "hair cells" to "catch" sounds (vibrations) and transform them into a signal that the auditory nerve can get to the brain. Different lengths of hair cells catch different wavelength of sound. Hi

        You're absolutely right that noise-reducing headphones most likely help rather than hurt. However, your statement about hearing loss being caused by high-frequency sound is incorrect. Loud low-frequency sound is much worse than loud high-frequency sound, because the loud sound has to travel along the entire length of the cochlea to reach its intended destination, and it causes damage along the way. The reason you lose high-frequency hearing first is that the high-frequency region of the cochlea is closest to where the sound comes in, so that every loud sound that hits your ears passes by that region and causes damage.

        Preventing significant hearing loss is easy - don't blast music, and give your ears a rest once in a while. It's kind of like not staring into the sun all day, but for your ears.

    I find, when walking down the street - that I've got my iPod's volume up to the highest level. It's not because I really like the song, and want to hear it really loudly, but rather, I can't hear it if I turn it down at all. Simply because of the passing traffic is so noisy.

    Had I kept the iPod down to a lower level, say at 0.75 or 0.5 - then I simply wouldn't be able to hear it - so, perhaps the problem is not the music players, but rather, an increase in noise from other locations? For example, traffic?

      It also doesn't help that iPods come with earbud-style headphones. If they came with larger ones that covered your ears, then you wouldn't have to turn the volume up so loud to hear it.

      • I just bought these headphones: http://www.amazon.com/exec/obidos/tg/detail/-/B00 0 065BP9/ [amazon.com]

        They offer really good sound isolation (I sat next to the engines in a loud airplane last month and when I wore them I heard almost nothing).

        They are a good alternative to sound cancellation - if you don't let sound in, you don't need to cancel it with iffy technology. Plus it costs less than 10% of the money and gives superb sound quality (not audiophile, but the best you can expect for less than a 100 imo).
      • in-ear-canal phones like the shure and etymonics do just as good a job in reducing outside noise as the active cancelling ones, plus have much better quality drivers to boot (and don't require batteries). My Shure e2c's are better that any headphone I've ever tried, and the volume on my jukebox seldom goes above 20%, compared to a around 70-80% with normal earbuds. And they only cost about US$70. The next up in the range are supposed heaps better still, but at a cost (one, day, she will be mine, oh yes)

      Headphones with active noise canceling will help with that. Where I used to keep the volume at 75% or more, I now rarely bump it above 30%.

    • I like quiet, so sometimes I use noise cancelling headphones. Good ones can be expensive but worth it to keep my sanity - plus I have a reason not to hear the phone :)

      Anyway, on the few times I use it to play music versus regular pairs of headphone, I notice that I don't have to set the volume up nearly as much.

      It's not just mp3 players, it's car stereos (especially the 1000+ watt "boom cars") and loud exhausts. Some of the cars on the streets in my town can produce sound pressures that are actually painful -- from a distance of ten feet, in another car, with the windows up!!

      Even base stereo systems these days are 60+ watts. That's enough to cause substantial hearing loss in a matter of weeks if listened to repeatedly, for an hour or more per day.

      I can't even imagine how profound the boomcar boyz hearing loss must be. Not that I care... karma and all that.

      Ever attended a rock concert? It's a near certainty that you did permanent damage toyour high frequency hearing.

      Bring lawn tools into the equation (leaf blowers, lawn mowers, chainsaws, etc.) and that == more hearing loss.

      However, it's not just the under-thirty crowd. Many of our fathers served time in the military, when hearing protection meant sticking your finger in your ear before the guy next to you threw a grenade or fired a 30.06. Hearing loss didn't mean shit when your biggest concern was not being shot on a beach landing. The difference is the genX'ers are *choosing* to damage their hearing.

    Deafness is a useful adaption to the modern working environment. A touch of deafness blocks out the computer fans, the traffic noise, the endless airplanes flying overhead, the neighbour's kids, and the wife. The only problem is that it takes more and more volume to produce that "oh, yeah!"effect when listening to music. But that's someone else's problem.

    Personally, I went partly deaf at the age of 16 from spending too much time on a firing range. But most of my peers went similarly deaf not from the iPod, but from the Sony Walkman.

    This story is about 25 years too late. I guess each generation reinvents the "we went deaf because..." story.

    This could happen regardless of whether you use a portable music device or not. Anyone who goes out to clubs will be exposed to loud music anyway, and in that kind of setting you can't control the volume.

      I was going to suggest exactly the same thing. My er6is are a godsend in noisy environments. When I stick them in my ears, I can't even hear a person talking beside me. An added bonus is that because there's no background noise, you don't need to turn up the volume as much. Of course, there are cons, like the inability to hear warnings, phones, and such, but you have to take that into account when you decide to use them. I keep the phone where I can see it ringing, keep an eye on the receptionist when I'm waiting for an appointment, etc. They're basically like earplugs that can play music.

      Etymotic also makes sound attenuators for use when you actually want to be able to hear what's going on. They reduce sound by approximately 20dB in a fairly linear way, which is great for obnoxiously loud concerts, clubs, etc. They're pretty cheap, too.

        I got a 30GB 4G iPod ("The iPod Formerly Known As Photo") recently. A friend who works at Apple also recommended the ER6is, and I ended up getting a set of those too.
        The safety concerns are real. I probably wouldn't use them biking or around outside in a city, because you really can't hear what's going on around you. But on commercial airline flights, they are amazing. It can actually be startling to remove the earphones mid-flight and hear how loud the engines are. What's really weird is that you can indeed listen to your music at a volume that would be completely drowned out by the ambient noise without the isolating earphones.
        As mentioned in the parent and grandparent posts, Because of the noise isolation, you don't have to turn up the volume a lot. I've heard a few people complaining about the bass response, but I attribute this to two effects. First, many people are used to listening to music in a way that would be appropriate for those ridiculous cars with the monster sound systems whose bass you can hear from a distance of several km. But even more important, I think the people who complain about the ER6i bass haven't properly inserted the 'phones into their ears. I believe this is a common problem. I've seen it mentioned in a few reviews of the ER6is, and Etymotic Research is even including a slip of yellow paper in the ER6i packaging now with the following message:
        IMPORTANT

        For Best results:

        Be sure to obtain a good seal.
        Without it, you will not have an optimal bass response.

        In some cases, slightly moistening the white eartips will help improve the seal in your ear canals.
        So if you're researching ER6i earphones (and possibly other noise isolating earphones) online, and you read reviews saying they have "no bass" or something similar, keep this in mind.
        Etymotic even makes optional smaller and larger eartips to allow for the correct placement and seal in ears that the standard eartips don't fit just right.
        I do recognize that bass may be in the ear of the beholder, so YMMV. It's best if you can find somebody you trust and ask that person's opinion. I was fortunate to have the ER6i earphones recommended to me by somebody whose opinion I've come to trust, and I've been more than satisfied with them.

    Didn't I read this same story about Walkman's 20 years ago? And didn't they decide the effects were negligable? Oh yeah I did. Abstract from a study in 1987: Krahenbuhl D, Arnold W, Fried R, Chuden H. Investigations on 50 high school students showed that this group had been using the "Walkman" only 1.5 h. per day during the last 14 months. A comparison of the audiometric results obtained with these 50 "Walkman" users, with those of 20 age-related non-"Walkman" users, showed no statistically significant differences. The investigation further revealed that to avoid hearing loss, an upper threshold level of 93 dB (A) should not be exceeded for a daily "Walkman" user time of two hours.

    I don't have an ipod, but I do listen to music through headphones. I'm a bit hard of hearing and for the past year or so when I listen to music I play it at the absolute lowest volume that I can hear it. Maybe it's just in my mind but I've noticed an improvement in my hearing. Not to mention it's less of a distraction to my development (and/or slashdot postings).

    Consequently, this behavior makes me realize that I need a quieter PC case. I've got a home made hack job case too many fans. I think it's time to upgrade to a professionally built case that would be quieter but I'm still having a hard time justifying dumping $150-$300 on a case.

    After that I've still got fish tanks that make a significant amount of noise. Not much I can do about that other than keep the water levels full or get rid of them alltogether.
    • Consequently, this behavior makes me realize that I need a quieter PC case.

      A while back I tried to figure out how to do this on the cheap; I eventually ended up with the computer box in the attic, with long wires connecting up the keyboard and monitor. USB was ideal for I/O, but I didn't have a USB CD drive so instead I used a slightly over-spec IDE cable --- which eventually turned out to be unreliable if I had DMA turned on, which was less than ideal. If I were doing it today, I'd use Firewire.

    I'm deliberately starting a new top level thread because the previous poster on this is getting negative moderation on some of the replies, and there is then no point in responding to them.

    Noise cancelling headphones if correctly implemented are rather more complex than just inserting an inverted signal. For the record, I am deaf (artillery and large engines, as if you care) and because of the strange hole in my hearing response I use a digital hearing aid. The configuration screen for programming this runs to a number of pages, and I can have it set to include or exclude things like refrigerator and fan noise. In fact, I have one program that does optimised noise cancelling to get the best speech response, and another that does no noise cancelling which is useful for music and for checking that things like HDDs are making the right noises.
    Noise cancelling technology is already used in professional telephone headsets, and I am surprised that it is missing from iPods and the like. It would be easy enough to have a button which switched between cancelling and not cancelling external noise sources and which, like my hearing aid, has a setting which allows through a sudden loud noise when in N/C mode, as a safety factor in traffic. This would mean the ability to listen at lower volume levels in noisy conditions.

    I have a local inductive loopset (one of the few good things to come out of Nokia in my view) which allows me to use the cell phone and to inject another sound source. With the hearing aid switched to inductive pickup only, and to block external sound, I can make a phone call in noisy conditions without difficulty.

    Conclusion: the technology exists to fix these problems and enable people to listen at lower volumes, manufacturers just can't be bothered.

    • one problem. once you inject all that noise cancelation, any audiophile with 20/10 hearing is going to snort in disgust at how bad it sounds vs "unfiltered, 500 dollar amped" stuff.

    Noise cancelling or isolating headphones.

    Etymotic, Shure and Koss all make noise isolating headphones, which are generally cheaper and have higher quality sound than noise cancelling gimmicks like the Bose headsets.

    Basically, you put in a set of these ear-canal plugs, you hear nothing but the music, and therefore can listen to your music at far lower levels in noisy environments than you would be able to with normal open or closed can style headphones.

    The isolation from the Etymotic ER-4p/s for example, is 44 decibels, which is phenomenal. I own a pair of Er-4ps myself, and have used them a lot while travelling, and have to say that spending 300 euro on a set of headphones does not look like a waste of cash once you get up to 30,000 feet in a packed Airbus.

    The isolation is so complete that it's shocking to hear the noise levels that everyone else is being exposed to once you pull the headphones out after a period of use.

    Not to mention the fantastic sound quality.

      It comes from damage to degeneration of the nerves in the inner ear, or so I've been told.

    Anyways, I can always turn off my hearing aid if things get too loud. :) I could have a surgery to regain hearing but I think I will use my partial deafness as an advantage. Turn it off, and poof. Less audio to hear for me.

    People will look at you funny, but earplugs with headphones is the right answer. You can eliminate all the background noise, and play the music at a level that (after passing through the earplugs) is safe. Foam earplugs are available at drugstores - 20 - 30 pairs for about 6 dollars. To really do it right, get a nice pair of circumaural headphones like Sennheisers.

    I've been thinking about this for years, in a minor way off and on, and I'm still waiting for someone to invent a good feedback system for hearing level. If the music can be heard clearly at 80-85db, thenit is probably safe, right? However, all the studies I've seen measure db in the environment, not the energy approaching the ear. And if you're wearing earphones, how do you prevent hearing loss when you don't know what you are delivering to your ear?

    Reactive noise-cancelling earphones would seem to be a good idea, especially if they can reduce the ambient noise to 50 or 60db and alow music to be heard at less than 85db. In fact, without music, I would be relieved sometimes to have noise-cancelling headphones to simply provide some near-silence. It would be a worthy project for competent technicians to come up with an inexpensive (less than $20) noise-cancelling headphone with signal contrast (outside noise less than 50db to inside noise less than 85db), easy equalization, and galvanic skin response sensors to indicate when the music was causing discomfort. (GSR might not be sufficient. Many recent studies showed that the type of music listened to can produce a variety of emotional and chemical responses ranging from peaceful, healthy, joyful to irritated, angry and unhealthy. Here's a a different question: If you knew loud rap and metallic rock were as bad for your system over the long run as cigarettes, would you quit listening to it?) An article written in layman's terms with good references can be found here: http://www.headwize.com/articles/hearing_art.htm [headwize.com].

    Although the general consensus is that much hearing loss is irrepairable, I have heard rumors of people recovering some hearing ability by listening to specific music. (I think I first saw this in a book called "Superlearning 2000", and have heard subjective reports since then, but I haven't noticed any scientific papers.) Also, if high-frequency loss is a problem to you, I've heard good things about Echophone.

I just tried mine at around that volume with the normal headphones and found it uncomfortably loud. Apart from anything else, I could tell which song was playing from the other side of the room, so anyone listening that loud on public transport deserves to go deaf.
    I had always assumed that the only reason it went so loud was for powering external speakers etc.

    You do not want to exceed 95 dB, ever: EVER!

    Take it from a deaf person whose hearing loss is averaged as 64 dB at 20Hz down to 95 @ 8 KHz. That is the surveyed threshold for a lifelong usage of a hearing aid without losing ones remaining hearing (thus rendering such hearing useless).

    Hearings is not recoverable as the many tiny cilia hair nerves gets shortened at greater than 95 dB due to excessive POUNDING of the noise whipping these reed-like cilia back and forth (tearing or cutting off blood flows) as amplified by your middle ear bones and outer ear's ear drum.

    Protect your ears, take it from a deaf person. It is career threatening in your mid-life. No need to get another cow during your mid-life crisis.

    Cholear implant (CI) is a proven technology, but a bothersome hinderance to those late-deafened teens and adult as they did not grow up accustomed to these CI outfits. (Doable, but takes longer to get accustomed to these CI). CI is not a perfect replacement as you would get 32 channels (more later) spread across the sound spectrum but with GAPS in between. Computer/signal processors back-fills in these inter-channel gaps (not pleasant to a true classic music afficiandos).

    Keep it down... It might save your life.

    I believe (though trying to find it on www.eu.int [eu.int] looks tricky !) that the EU has statutory maximum volume limits on audio devices where headphones can be attached (but I could be wrong on this). Mind you, I just bought a new MP3 player [mymemory.co.uk] that is "comfortable" volume in the 15-25 range, but it can go to ear-bleeding "40", which I suspect is way above the EU limits. Strange, though, because I have another player [mymemory.co.uk] that the same site sells and that's got a much lower maximum volume.

    I have mild hearing damage in my left ear, unrelated to headphones. In my case, it has to do with years of practicing the violin without an earplug in my left ear (which is most vulnerable to damage in violinists).

    Nevertheless, I think the iPod generation is in luck, because they are also one of the first generations where genetic therapy is not purely science fiction. In the past couple of years, researchers discovered that the production of a protein (Rb1) was responsible for the behaviour shared by the inner ear hair cells of all mammals, or more to the point... the reason the hair cells do not divide and hearing does not regenerate. Recently scientists discovered the gene that was responsible for producing this protein in mice. Given 5 to 10 years, I am optimistic the naive iPod generation, senior citizens and even I will be eligible for gene therapy to reverse the effects of hearing loss.

    It is important to protect your hearing, but damage is inevitable no matter how careful you are. Luckily, for musicians and the ignorant iPod generation, there is a glimmer of hope on the horizon :)

I can notice a diffrence in the hearin on the right and left sides of my own head from the minor damage over the years. The hearing in my left ear is much more acute overall, and can hear frequencies that the right one cant.
