So, remember that virus that communicates using high-pitched sound? If no, here's an article:

This article says that the Furby communicates in the same way. It would be interesting if the Furby was a vector for spreading messages via this virus. Very, very interesting.

I doubt this (Furbys are kiddy toys, after all); but this article proves that audio is indeed a viable data communication channel for bypassing air-gaps.

lets ban audio

"Furby: Approved for use in non-pressurized compartments of the International Space Station (only)."

New security measure, from now on I will only allow our user to use their PCs in this room.

If anything, data over audio would be easier in an anechoic chamber since you don't have to worry about reverb or background noise.

US Military guidelines do require acoustic isolation of all SCIFs (Secure Compartmentalized Information Facilities). You just need isolation, though; deadening the rooms is not really necessary.

Someone should invent some sort of general modulator/demodulator and use sound to connect computers to the Internet!

Not sure if this is sarcasm...

Oh come on, calling it a modulator/demodulator totally gives it away :)

I like to give the benefit of the doubt but in general I just don't trust comments on HN anymore.

Plus doing it with light is just way cooler.
