Pretty much every other part of 1984 has come true somewhere or other, why not that?

- apotheon 17y agoActually, that works for speakers -- since most speakers for a computer are designed in a manner that is identical to a means of designing a microphone (just with some of the dimensions altered for quality of sound, et cetera). I'm not so sure a similar principle would work for, say, an LCD monitor or CRT.
- jacquesm 17y agoIt definitely does not work for an LCD monitor or a CRT, I can guarantee you that. You're right about the loudspeaker and the microphone example though, since in the most common cases loudspeakers are electromagnetic devices that convert electricity to air pressure in front of a cone, and vice versa. In fact, almost every piece of electronics can function as a microphone (Coils, capacitors and so on), I built transmitters a long time ago and the measures you have to take to get rid of spurious microphony are pretty draconian.
