The car cabin is extensively used as a listening environment for various audio programs,
such as music, video soundtrack, navigation system instructions, telecommunications, and …

This paper describes a method for focusing the reproduced sound in the bright zone without
disturbing other people in the dark zone in personal audio systems. The proposed method …

The acoustic environment in an automobile cabin has a significant effect on the perceived
quality of the vehicle. There are two components of the acoustic environment in the …

A superdirective array of audio drivers is described, which is compact compared with the
acoustic wavelength over some of its frequency range. In order to minimize the overall …

A recent approach to surround sound is to perform exact control of the sound field over a
region of space. Here, the driving signals for an array of loudspeakers are chosen to create …

The widespread use of loudspeakers on mobile devices to reproduce audio in public spaces
has led to issues of both user privacy and noise nuisance. Previous work has investigated …

With an increasing interest in personal audio systems, the car cabin is an important
environment in which to generate different audio programs in different regions, without the …

An application of current interest in sound reproduction systems is the creation of multizone
sound fields which produce multiple independent sound fields for multiple listeners. The …

Directional sound fields can be generated by arrays of multiple sound sources such as
loudspeaker drivers. These systems, though potentially capable of high levels of directivity …

The acoustic contrast control (ACC) approach provides a simple strategy to focus sound on
a designed target area in a personal audio system. All of the traditional ACC approaches …
