I still don't have an Internet connection in my apartment, but now it should be on it's way!
Meanwhile, I found that this years Ig Nobel Prize in acoustics was awarded to Kazutaka Kurihara and Koji Tsukada for creating the SpeechJammer. It's a device that disturbs people's speech by simply playing back what the person is saying, but with a tiny delay. I've experienced this myself working at the technical support of a major swedish ISP. Sometimes I could hear my own voice in the headset, with a delay, and it was tremendously difficult trying to talk to the customer without stuttering.
If I only thought of this application back then (2007), I could've been awarded an Ig Nobel Prize instead. Ah, well...
