This chapter describes the physical modeling and output-based measurement of
loudspeakers, essential hardware components in sound-field control. A gray box model …

Traditional loudspeaker and headphone design sacrifices efficiency for sound quality.
Nonlinear, adaptive control can compensate for undesired signal distortions, protect the …

In this paper, a first-order loudspeaker, which is composed of monopole and dipole units, is
designed and manufactured. The structure and size of the loudspeaker is shown. It is able to …

Existing literature on sound zone control generally consider the signal model to be linear.
However, this is seldom true in practice owing to nonlinear distortions arising from the …

Car interior sound field zoning is receiving increasing attention. The weighting factors are
generally used to balance the acoustic contrast and the sound field reconstruction error of …

Sound zones systems generate a sound field in a spatially confined zone while attenuating
the sound energy in another predefined zone within the same acoustic space. The goal of …

Sound design in cars, especially sound control, such as echo cancellation, noise control,
sound zones require highly linear and in most cases time invariant behavior of the audio …

Acoustical isolation in a shared space, eg, a living room, could be naturally achieved if the
users are located in different rooms or use headphones at the cost of limited social …
