This paper describes a method of generating a controlled sound field for listeners inside a
circular array of loudspeakers without disturbing people outside the array appreciably. To …

Reproduction of multiple sound zones, in which personal audio programs may be consumed
without the need for headphones, is an active topic in acoustical signal processing. Many …

Active noise control is an efficient approach in dealing with unwanted acoustic disturbances.
However, most of the active noise control algorithms aim to control the signal of the error …

Reproduction of personal sound zones can be attempted by sound field synthesis, energy
control, or a combination of both. Energy control methods can create an unpredictable …

This manuscript presents a method for reproducing sound fields actively by using a vibrating
submerged structure as the field reproduction source, with the target sound field to be …

Sound zone systems aim to produce regions within a room where listeners may consume
separate audio programs with minimal acoustical interference. Often, there is a trade-off …

For some purposes it may be of interest to generate sound zones with different acoustic prop-
erties in a room. This paper compares two strategies for generating such zones. One method …

The control of the spatial distribution of noise and sound has been widely investigated for
achieving passive and active noise control. By extending the concepts of active noise control …

A recent study has shown that a circular double-layer array of loudspeakers makes it
possible to achieve a sound field control that can generate a controlled field inside the array …

Techniques such as multi-point optimization, wave field synthesis and ambisonics attempt to
create spatial effects by synthesizing a sound field over a listening region. In this paper, we …
