    Ho Ho Ho Happy Holidays everyone.

    Recently I just got a new IKEA desk. Somehow this desk has a very different resonate from my old beat up solid oak desk. I put my iMac on it, now it makes a very low pitch (around 60Hz) humming noise, it is not very noticeable in daytime. But at night when it's very quiet, it gives me a headache!!! One of those thing once you noticed, it will just bug you. Does anyone know if there is something like a pad that I can put under the iMac to absorb this vibration?

    This problem, prone to people sitting behind desks this time of year is known as "Scrooging", especially when you see it as a chance to get some extra work done. It causes the humbug. Humbug. Should be gone by the 26th. ;)

    Oh, and here we call it iKea.

    Go and get a piece of anti slip matting. Put a layer or two down and done

    Maybe try a towel to test if your theory is correct.

    I always use acoustic foam or use custom speaker decoupling devices, (Primacousic or Mopads) alternatively glue a floor tile on top of foam it should do the trick..

    Thanks all for your replies. According to VAvW, the hum should go away today but it persists! Damn humbugs! :eek: Seriously, the acoustic foam sounds like a good idea.
