Measurement and modelling of head-related transfer function for spatial audio synthesis
TL;DR: An important finding of this thesis is that the HRTF decomposition with the spatial basis functions can be well approximated by a finite number, which is defined as theHRTF spatial dimensionality.

Patch nearfield acoustic holography in a moving medium
TL;DR: In this paper, a patch nearfield acoustic holography (NAH) in a moving medium is proposed, which not only reduces the influence caused by the limited aperture effects through sound field extrapolation, but also perfectly suits for sound field reconstruction in moving medium by improving the shape of the modified Tikhonov regularization filter and the noise estimation method in accordance with flow effects.

Cartesian Cut-Cell Method with Local Grid Refinement for Wave Computations
TL;DR: In this article, the authors simulate the sound radiation produced by oscillating baffled pistons, using both linear and nonlinear model, and consider the interplay between wave propagation and geometric complexities.

Design framework for spherical microphone and loudspeaker arrays in a multiple-input multiple-output system.
TL;DR: A design framework for MIMO systems based on a model that addresses errors and highlights the importance of a matched design is developed, demonstrating the superiority of a matching system over an unmatched system in the synthesis of directional room impulse responses.
