    anythime i hear about speakers going to eleven i think of that movie "We are Spnal Tap" or something

    Band Member: you see, normal speakers go up to ten, these go to eleven.
    Some Guy: why don't you just make that ten?
    Band Member: these go to eleven, they are louder.
    Some Guy: no, why don't you make eleven ten, so they're the same volume?
    Band Member: but these go to eleven
    Some Guy: ...

    then the part "our F***in' stonehenge was in danger of being crushed by a f***in midget!"

    if the brown noise makes you crap yourself, what would the white noise be? :naughty:

    *white noise is static, leave it on long enough and you won't notice it, but since you are ignoring a certain loudness of noise, everything sounds quieter

    Um note the movie "white noise". It is soposedly were you can hear spirits, but some say it is the wind some say it sounds like waves other hear other things infact I havnt ever realy heard true white noise(Tv white noise isnt the true thing.). And what was this pink noise, seeing how high you can here, is there like an mp3 like for that brown noise mp3 thingy.

    white noise is an urban legend saying you can hear the voices of dead people sometimes if you leave a tape recorder on dictate at night (dictate records any noise it hears, but it doesn't turn if there is no noise. you can get two hours of talking on a tape instead of ten minutes total of intermittent talking)

    i think pink noise is a frequency that only some people can hear, about 20kHz. it's not fun.

    is the noise a physical effect? (i can feel heavy bass on my chest at concerts)

    or is it a hearing thing? (i want to burn this on a CD and have a friend listen to it in class :hehe: )

    also it could be a cure for constipation...

    I was brought up to believe pink noise was all in the audio band, white noise covered sub- and super-sonic as well, but he says not. :confused:

    White noise has the same signal level at all frequencies where as pink noise has a defined roll off. IIRC the roll off for pink noise is -3dB fer octave , with the lower frequencies being the highest signal level. AFAIK pink noise is exclusivly used to test audio devices like loud speaker frequency response and the roll off is to compensate for human hearing, i.e. we can hear high frequencies at a much lower level than low frequencies. I would assume that white noise would be used to test things like antenna and tuner response. Neither has a set frequency range... just a definition of what one frequency level is compared to another.

    Oh, right on! Being an audio nerd, I've always wondered about this. Plus, I love Mythbusters, so I'm definitely watching this one!!! Thanks for the heads-up!

    Hate to resurrect this thread, :blush: but I watched the Mythbusters episode, and myth busted! Adam, wearing Depends (Adult diapers) was surrounded by 5 huge banks of speakers and blasted with up to 143db of tone from 6 Hz to about 20 Hz. Nothing happened. It was interesting that the people around him all felt a bit agitated, but no one was running for the bathroom.

    When the speakers were pumping out 6 HZ you could hear the speakers extending, but of course, not he tone. When he spoke, his voice would vibrate at the same frequency. But again myth busted for sure.

    theres a UK program called Brainiac: Science Abuse on Sky TV, i watched that and they claimed they transmitted some brown noise with the program, and i went for a heffa of a dump when they said they were doing it, might have just been a placebo though...but i think it does exsist.
