  Abstract: Sound Localization connects physics to biological systems and everyday experience, as well as the simulation of everyday experience in video games and musical recordings, while it also synthesizes and reinforces basic waves principles – phase, wave speed, diffraction, reflection, and spectrum. This poster presents a sequence of introductory-level experiments students can perform using the free sound processing program, Audacity, to explore the fundamental wave physics responsible for sound localization cues: Interaural Time Difference (delays in sound's arrival at one ear vs. the other), Interaural Level Difference (variations in sound intensity at one ear vs. the other), and the effect of Anatomical Transfer (differences in a sound's spectrum due to reflection from and diffraction around the head and upper torso).
