Abstract: A vehicle individual sound zone(ISZ) prototype is developed in this paper, which enables the driver and the rear right passenger can experience independent sound field environment. This is realized by the development of a real-time ACC-PM-based ISZ algorithm as well as the related software and hardware.The sound compartmentalization effect of the prototype is approved by both objective and subjective tests.
Key words: individual sound zone; prototype system; algorithm development; test and evaluation
