Skateboarding

A skateboarder recorded on the plaza of Technische Hochschule Nürnberg Georg-Simon-Ohm. The hard tiled surface produces a distinctive impulsive sound source as the skateboard wheels interact with the ground. Versions vary the trajectory of the skateboarder — linear passes versus full 360° circuits — and whether background music from a Bluetooth speaker is present, enabling controlled study of moving sound source salience.
