Abstract

Listening tests were conducted to evaluate the perceptual influence of adding a lower layer of loudspeakers to a setup that is commonly used for immersive audio reproduction. Three setups using horizontally arranged loudspeakers (1M, 2M, 5M), one with added height loudspeakers (5M+4H), and one with additional ?oor level loudspeakers (5M+4H+3L) were compared. Basic Audio Quality was evaluated in a sweet-spot test with explicit reference, and two preference tests (sweet-spot and off sweet-spot) were performed to evaluate the Overall Audio Quality. The stimuli, e.g., ambient recordings and sound design material, made dedicated use of the lower loudspeaker layer. The results show that reproduction comprising a lower loudspeaker layer is preferred compared to reproduction using the other loudspeaker setups included in the test.
