Abstract:

In the process of vehicle intelligence, in-vehicle sound field zoning control technology plays a crucial role in enhancing the acoustic experience within the cabin. In this paper, a comprehensive review of in-vehicle sound field zoning control algorithms and their application are provided. Firstly, the background and theoretical basis of the technology are introduced. Then, the development process, control principles, and characteristics of various sound field zoning control algorithms are thoroughly analyzed. Finally, based on the existing research progress, the potential advancements in sound field zoning control technology with regard to reproduction accuracy improvement, algorithm robustness, and sound field uniformity are explored, and a series of challenges limiting the widespread application of the technology in vehicles and the solutions are discussed. The review aims to provide reference for further research on in-vehicle sound field zoning control and to promote widespread application of the technology in the vehicle industry.

Key words: in-vehicle sound field control, loudspeaker array, sound field zoning, control algorithms
