Boing Boing reports that bathroom hand-dryers “suck in poo-particles and aerosolize them all over you and everything else.”
So unless you want some aerosolized feces with your tinnitus, just say no to excruciatingly loud–and disgusting–electric hand dryers.
Noise disturbs man and machine
Boing Boing reports that a “group of Princeton and Purdue researchers have demonstrated a successful acoustic attack against mechanical hard-drives.” How? They played a low-frequency noise “keyed to the resonant frequency of the drive components” nearby, which caused the drive to vibrate so it could not be read or written to.

Once you teach a computer to see,
Shhhh. It can hear you.
it can teach itself to hear. MIT’s computer science department, “using software image-recognition to automate sound recognition,” found that “once software can use video analysis to decide what’s going on in a clip, it can then use that understanding to label the sounds in the clip, and thus accumulate a model for understanding sound, without a human having to label videos first for training purposes.” And humans are rendered even more useless than before.
