Auditory Motion lab technical info
Introduction
The Auditory Motion Lab is a facility designed for experiments involving moving sound sources. 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. The system is controlled by a PLC controller from Panasonic. The sound system is controlled by a RZ6 multi I/O processor.
