Abstract

Personal sound zones allow people in different zones to listen to different audio programs without using headphones. It is proposed in this paper to use the active noise control (ANC) method to create bright and dark zones in car cabins with headrest loudspeakers, and its performance is compared with the most commonly used pressure matching (PM) method. Numerical simulations based on a finite element model of a car cabin show that the ANC method can achieve similar acoustic contrast control performance to that with the PM method with fewer channels, and the adaptive algorithm has the potential to be applied in the system. The experiment results obtained in a mid-trim level A-class sedan are presented to support the findings in the simulations, and subjective experiments are carried out to evaluate the performance of these two methods.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
