In order to control an acoustic field inside a target region, it is important to choose suitable
positions of secondary sources (loudspeakers) and sensors (control points/microphones) …

A new impulse response (IR) dataset called “MeshRIR” is introduced. Currently available
datasets usually include IRs at an array of microphones from several source positions under …

A wave field estimation method exploiting prior information on source direction is proposed.
First, we formulate a wave field estimation problem as regularized least squares, where the …

Multizone sound field reproduction for synthesizing desired sound fields has various
applications. The modal matching-based method can obtain global modal coefficients to …

All spatial active noise control (ANC) systems, when deployed in typical room environments,
have time-varying acoustic channels between the secondary sources and the error …

In literature, particle velocity has been introduced to improve performance of spatial sound
field reproduction systems. However, all existing work requires to have accurate particle …

Two sound field reproduction methods, weighted pressure matching and weighted mode
matching, are theoretically and experimentally compared. The weighted pressure and mode …

A multizone sound field control method, called amplitude matching, is proposed. The
objective of amplitude matching is to synthesize a desired amplitude (or magnitude) …

Mode-matching based multizone reproduction has been mainly focused on a purely two-
dimensional (2D) theory, where infinite-long 2D secondary sources are assumed for 2D …

Sound field control systems deployed in room acoustic environments require knowing the
acoustic channel impulse responses between the loudspeakers and matching microphones …
