Parametric Loudspeaker: From Theory To Applications
This talk highlights a comprehensive overview of research and technical advances related to PALs, covering modeling and simulation computation, measurements, signal processing, beamsteering, and their implementation and application.
Overview
Parametric array loudspeakers (PALs) that can achieve directional sound reproduction have received widespread attention from researchers and engineers due to their advantages of narrow beam, strong directivity and no side lobes. PALs have developed rapidly in theory and application and have been used in various commercial products. At present, PALs have become a research hotspot in the field of audio engineering. This talk highlights a comprehensive overview of research and technical advances related to PALs, covering modeling and simulation computation, measurements, signal processing, beamsteering, and their implementation and application. Finally, some technical challenges and open issues are summarized to fully exploit the benefits of the directional sound reproduction.
