Auditory Motion lab technical info
Introduction
The Auditory Motion Lab is a facility designed for experiments involving moving sound sources. This lab enables researchers and students to explore how we perceive sound in dynamic environments, offering insights into auditory processing and spatial hearing.
The lab features a soundproof booth, ensuring an isolated testing environment. At the heart of the lab is a two-axis robot arm suspended from the ceiling. This arm is equipped with a high-fidelity speaker capable of moving at a fixed distance around the subject's head. The centrally placed chair, which can rotate on its vertical axis, allows subjects to experience sound from various angles. Head movements are tracked using a 3-axis electromagnetic field (EMF) head tracking system. Additionally, wall-mounted speakers facing the subject provide ambient or background sounds to enrich the experimental scenarios.
In this lab, students and researchers conduct experiments to understand how motion affects auditory perception. Studies range from simple sound localization to complex scenarios involving moving sound sources and background noise.
