Something odd I noticed today
by hazel from LinuxQuestions.org on (#5BQYT)
My computer has a resonant hum, probably because it's a largely empty case (basically it consists of laptop electronics inside a tower). Occasionally the hum gets quite loud but mostly it's quiet. Probably the vibration comes originally from the disk drive.
Today, when I switched the computer on, I happened to have the washing machine running in the kitchen and I noticed to my surprise that the frequency of the sound it made was almost identical, perhaps very slightly sharper. Yet the computer's case is much smaller than the washing machine. I wonder what determines these things.
