I have a Linksys wireless router (WRTG54) near a I/O Magic Sound Assault IHD51 (a 5.1 surround sound headphone with a volume control/bass amplifier box). This control box seems especially sensitive to interference caused by the transmission of wireless signals. I recreated the interference by placing the control box between the router antennas (for maximum signal), and recorded through Audacity from a microphone placed in between the headphones. I then took the cleanest-sounding 1-second cycle and looped it for 10 seconds. Finally, I did a reduction of the computer fans' background noise (that's the low hum in the background), and exported to ogg.
