Acoustic Internet Macroscopy


Test your Net connection with a twang

access 
Listening to an Internet connection is a better way of testing its quality than the current practice of "pinging," reports NewScientist.com. Chris Chafe, a cellist and director of the Center for Computer Research in Music and Acoustics at Stanford University, discovered a new method of detecting microsecond variations in the steadiness of an Internet connection. It involves converting variations in a jitter (the variation of a ping and its return over time) to musical notes. Musicians are able to detect tonal variations, thus the longer the transmission time, the lower the pitch of the note produced. Quality connections are vital in new areas such as telemedicine, where a remote surgery is required and large data packets have to be transferred quickly and accurately.
