    I have tried several mb and mbp, and they all cause a very high pitched noise in my ear, similar to a tinnitus. this noise is not really noticeable right away (like the inverter-caused noise that some 17 inch hi-res sr mbp seem to have).
    the sound appears after a while of use, and it stays pretty long time. it really bothers me quite a lot.
    (old macbooks did not have this issue. that's why I think it is the led-display.)

    I don't know what to do - I just want to use one these macbooks. they are awesome machines besides this strange noise issue.

    i have tested it by recording through a microphone, and there is a very little audio peak round about 19500 hz - but this may also be the hard disk.

    does anyone happen to have experienced similar problems?

    Can't say I've heard anything from my 15". Then again I've been to too many loud gigs and with age my audible range is dropping!

    my mothers macbook 2.0 makes that while using windows, it goes up when you push the brightness.
    my 2.53 doesnt make a sound though. but i havent tried it under windows yet.

    dont bother showing this to anyone over 22, they wont hear it, perhaps a musician or audio engineer, nobody else :)

    I can't hear anything from my 2.53 MBP (sign). I'm 22 and I'm fairly easily annoyed by sounds like the one you're describing. Thankfully it's quiet.

    MacBook Pro's have had a LED backlit display since 2007, so the old ones should sound like the current ones. I doubt that's the issue here.

    Maybe try some good quality high freq earplugs. If the problem is not resolved then at least you eliminated the MBP being the problem. Low level sound like that would not be transmitted by bone conduction.
