Reconstruction of the sound field in a room using compressive sensing [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2018
Capturing the impulse or frequency response functions within extended regions of a room requires an unfeasible number of measurements. In this study, a method to reconstruct the response at arbitrary points based on compressive sensing (CS) is examined.

Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]

open access: yesJASA Express Letters, 2021
Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10].

Construction and selection of a directivity wave function improving ill-condition problems in equivalent source method based near-field acoustic holography

open access: yesAIP Advances, 2021
Sound-field reconstruction via the equivalent source method presents an ill-conditioned problem. This paper proposes a method in which traditional monopole equivalent source spherical wave functions are replaced with strong directional wave functions ...

Three-Dimensional Modeling of Sound Field Holograms of a Moving Source in the Presence of Internal Waves Causing Horizontal Refraction

open access: yesJournal of Marine Science and Engineering, 2023
In this paper, we study the variations of holograms of a moving source in an inhomogeneous ocean waveguide. It is assumed that intense internal waves (internal solitons) are the reason for the inhomogeneities of the shallow water waveguide.
