I am excited to see that scientists are FINALLY using their powers for evil and not good.
"The Annoy-a-tron generates a short (but very annoying, hence the name) beep every few minutes. Your unsuspecting target will have a hard time 'timing' the location of the sound because the beeps will vary in intervals ranging from 2 to 8 minutes. The 2kHz sound is generically annoying enough, but if you really really want to aggravate somebody, select the 12 kHz sound. Assuming you have done your part in selecting a suitable hiding location for the Annoy-a-tron, it will do its part to drive your co-workers slowly mad with its short and seemingly random beeps."
I know what I'm bringing to the next dinner party in Pasadena!
