This is what background noise sounds like when you, first set your recording to automatically reduce noise, except to get this sound, put mic on sensitive, then increase the volume. Voila! computer noise!.
I took an rca to 1/8 inch cable and plugged it into my sound card input. The sound is created by sticking the two rca plug ends to a 9 volt battery's + and - terminals. . . I don't know if the noise comes from the battery or the computer, though.
This is the sound of wind as generated by my naturalnoisegen program. Naturalnoisegen uses several timed generators to produce complex natural noises. In this case, 80 low-frequency generators were used.
Another example on "listening" to a computer. Many sounds you hear are overtones from fans. The sharp noise is data transfers. Most of the sounds are caused by moving the mouse. The processors are not "heard" by placing a small antenna between the flat cables from two hard discs, you can capture the data packages. That may be done next time.

A recording of a computer connecting to the internet with a dial-up connection. I only edited it a little bit, just condensing it and removing background noise.
Randomised beeping sounds. Sounds like a "futuristic" computer. Generated using the incredibly useful sfxr http://www. Drpetter. Se/project_sfxr. Html (i pressed repeatedly on the pickup/coin button :).
