Lateral Listener Movement on the Horizontal Plane (Part 2): Sensing Motion through Binaural Simulation in a Reverberant Environment

In a multi-part study, first-person horizontal movement between two virtual sound source locations in an auditory virtual environment (AVE) was investigated by evaluating the sensation of motion as perceived by the listener. A binaural cross-fading technique simulated this movement while real binaural recordings of motion were made as a reference using a motion apparatus and mounted head and torso simulator (HATS). Trained listeners evaluated the sensation of motion among real and simulated conditions in two opposite environment-dependent experiments: Part 1 (semi-anechoic), Part 2 (reverberant). Results from Part 2 were proportional to Part 1, despite the presence of reflections. The simulation provided the greatest sensation of motion again, showing that binaural audio recordings present less sensation of motion than the simulation.
