      personally I'd rather have the phone go down in silence and IF there's _any_ juice left let the phone wait untill the call is finished before turning off in a controlled fashion(also, it's less annoying if it just goes off without all the racket).

      Now imagine instead of an auditory disturbance in your middle ear, it was a balance disturbance in your inner ear. That's what vestibular neuritis is, which I got last year (presumably from a virus that somehow got through the tympanic membrane into my inner ear, though there were never any substantive middle ear symptoms, probably from blowing my nose too hard, though nobody really knows shit). It's like tinnitus of your balance system. About 6 or 7 weeks of my life were living hell - in a constant state of torturous dizziness, unable to walk farther than to the bathroom and back, and when I was in good shape, to the living room.


      The funny thing is by the time the otolaryngologist/otoneurologist got around to ordering all the tests and stuff, it had already started to abate somewhat (though the balance tests they did made me so nauseous and dizzy, I was back in bed for 3 days afterwards - won't be doing THAT again, despite the recommendation for 6 month follow ups). In my case, the damage to the vestibular system on the right side is apparently permanent - so it turns out that just like tinnitus, your brain has to adapt to the spurious signal coming out of one side of your peripheral vestibular system and learn to filter out what is essentially white noise. The brain, being an adaptible organ, is remarkably good at this - you become highly visually dependent for a while as the brain resets the system (can't look at the damned venetian blinds hanging in my own room, for example). Over time the visual dependence has abated, and I'm left with only a mild predisposition for motion sickness if I don't see EXACTLY what is going on, so I take dramamine and valium when I'm on a plane or bus or something.


      Anyway, you don't realize how dependent you are on your balance system until it stops working. Truly one of the most unpleasant experiences of my life. I wonder if tinnitus sufferers have one of the same long term symptoms that I have - a vastly increased sensitivity to caffeine and alcohol. I used to slug down coffee like nobody's business, but now if I have more than about 2 cups in a two or three hour window, it causes the dizziness to come back, and usually takes at least a day or two to abate, sometimes longer depending on how much I overdid it. It's like the volume on the white noise gets turned *WAY* up.


      And I still drink beer and wine regularly, but hard liquor is tough - if I do the kind of drinking I used to do in college and get really drunk, my balance system gets crazy on me, kicks out, and I puke everywhere (even if I am only moderately drunk). The aftermath the next morning is even worse - I end up partially-bedridden again for a week or so at a time.


      Okay, lest I sound like a cripple, I have learned to live with all this stuff, I just drink half-caf coffee or one small cup of caffeinated tops a day, and avoid the binge drinking, which makes me sorely miss my college days, but I just see it as the price of getting older (yeah, I'm a whopping 25 years old).

      So, unless your cellphone is expressing 115db ringtones, for over 15 minutes, and you're STILL listening to it, you have nothing to worry about. DUH!!!!!!

      A little knowledge is a dangerous thing. Some rough guesstimates--I'm in a bit of a hurry this morning, and someone is welcome to do a sanity check.

      Say the phone rings at perceived 85 dB when it's on your belt or in your pocket. That's loud enough to be heard over most traffic downtown, though you would likely miss it if a truck was going by. Figure the phone is one meter (a little over three feet) away from your eardrum.

      When the phone is at your ear, the speaker is maybe three centimeters (about an inch) from your eardrum. That's a reduction in distance by a factor of around thirty or so. Since sound intensity follows an inverse square relation, you're looking at about a thousand times as much intensity. The decibel scale is logarithmic, so that's an extra 30 dB right there, putting us at 115 dB.

      If the phone is a little louder than that initial estimate, or held slightly closer to the ear, we're moving towards 120 dB and up. Even if it's not doing permanent harm, those sounds are loud enough to be physically painful at short durations, especially if the person is listening intently and not expecting to be blasted. The startle response that's prompted could also be harmful.

      Worse; the sound is dissapating into the environment at your belt buckle, but will be directed into your ear if you have it at your ear when it goes off. You can probably tack on another 3-10 dB for that, depending on the phone's construction. (Wide range there because I don't know the numbers, just the effect; for that matter it may come out over 10, I'm just not confident about it.)

      The inverse square law is for a perfectly spherical emitter in an obstacle-free environment (a sea of air), in reality it can be a bad over- or under-estimate, depending on whether the sound is being directed toward or away from you. This is one of those cases where it an under-estimate, possibly a very bad one, because the sound is fairly directional by design, and when held to your ear, it is directed right into it.

      As the sound gets more and more directional, the drop-off approaches 0; you can never reach that, but if you've heard about those ultra-sound based speakers that use non-linearity in the air to create audible sound, one of several reasons they are cool is their ability to be highly directional (higher frequencies can be more directional), so you can beam sound across a football field if you want, since the sound's directionality borrows the characteristics of the ultra-sonic frequencies. Cute trick.

  33. Ericsson And Sony-Ericss phones have similar flaws by djace · · Score: 4, Informative

    I've owned an Ericsson phone, and it had a similar flaw. After hitting the Automatically Redial option when a number is busy, when the phone is able to go thru, it plays a LOUD tone. And, this is done even when the phone is on "Silent" mode. Newer Sony-Ericsson models only do this when the "Silent" mode is off. Even though, nowhere in the manual does it say that you should NOT hold the phone next to your ear when using the Automatically Redial option.

    Older siemens mobile phones had two speakers. One was normal speaker and the other was just for ringing. When batteries reached minimum the ringing speaker sounded with ear piercing beeps but fortunately the speaker was placed on the side of the phone.

    Todays phones have one speaker for both communication and ringing. So siemens probably sticked to their software design and implemented it in the modern phones. The result is obviously not so satisfying considering those high pitched tones resonating in your ear.

  36. Example of bad sound code... by feidaykin · · Score: 3, Informative
    I was using a friend's computer... this friend just happened to have the fancy Klipsch THX certified speakers, which cost a pretty penny... Anyway, we got to talking about old DOS games and this one called "Acid Tetris" came to mind, and for nostalgia purposes, we decided to download it. My friend was a little concerned something "bad" would happen running such an old DOS game in XP, but I was confident since I've run games like Dune II without any major issues, and besides, the worst that can happen is it just won't work... right?

    So, so very wrong. The instant it opened an eardrum-shattering scream let loose through the mighty, three figure dollar amount speakers. I instantly closed out the game only to find that a persistent buzzing sound was present. At this point I think my friend stopped breathing (fearing the speakers were totally ruined) and I thought, hey no big deal, I'll just reboot. Buzz sound was still there. Well no big deal, let's just power down and unplug everything. Buzz sound still there. I didn't think it was that bad, but this nameless friend of mine couldn't stand it and bought new speakers.

    And I now have a pair of Klipsch speakers that make a rather obnoxious buzzing noise. But they were free! So, in a sense, this bad sound code that almost ruined these speakers (they're worthless in dollar terms, no way I could sell them on eBay, etc) also provided me with free speakers that I never would have bought with my own funds.

    I must therefore both curse and thank the developers of Acid Tetris, and more likely the folks in charge of backwards compatibility at Microsoft, and my own stupid self for running an old program and trusting XP to not bork itself.

    If you've read this whole thing you're a brave, yet sad soul... but stay tuned for further adventures in computing with your hero(or nemesis?), the one and only Michael "Mad" Raymer!

      It sounds like your friend hadn't set the volume levels correctly.

      Most likely, the speakers were set to a very high volume, and this was compensated for by setting the volume level on Windows XP very low. The old DOS game ignored the WinXP volume level, and produced the maximum output the sound card was capable of.

      If the speakers were set to produce a loud but non-destructive level of sound at the soundcards maximum output, this would never have happened. However badly the game was designed, it could not have made the soundcard produce an output higher than 5V pk-pk

      That was the bad thing with many MS-DOS games and early PC's, there was no audio control, as all sound was created by sending frequency as an 8-bit value to port 61h. If you were lucky, some games allowed you to switch the sound off. In order for me to play games at night or to play games with terrible audio, I had to lobotomize each game by doing an automatic disassembly and replacing E6 61 with 90 90.

      This replaced the instruction:

      out 61h,al

    That the Siemens Series 65 phone emits an ear bleeding shreak when starved for energy (and obviously attention as well) is just survival of the fittest. Other phones may be regularly left to starve until shutdown, but with the Siemens, that is likely to never happen a second time.
