A sparse equivalent source method for near-field acoustic holography [PDF]

The Journal of the Acoustical Society of America, 2017
This study examines a near-field acoustic holography method consisting of a sparse formulation of the equivalent source method, based on the compressive sensing (CS) framework. The method, denoted Compressive–Equivalent Source Method (C-ESM), encourages spatially sparse solutions (based on the superposition of few waves) that are accurate when the ...

A comparison of compressive equivalent source methods for distributed sources

The Journal of the Acoustical Society of America, 2020
Sparse sound-field reconstruction methods based on compressive sensing and the equivalent source method have gained a lot of interest in recent years, offering a wide frequency range. An irregular array must be employed, and the sound field must be representable by a sparse vector of source-model amplitudes.

Application of the equivalent source method to directional noise sources

Noise Control Engineering Journal, 2012
Prediction of noise levels at long ranges from such sources as flying aircraft or moving ground vehicles is an important practical problem. When terrain, wind, and atmospheric effects are taken into account, this problem cannot be solved analytically, and, thus, numerical solutions are required.

An investigation on source distribution characteristics obtained with the equivalent sources method

The Journal of the Acoustical Society of America, 2002
Although the equivalent sources method is frequently used to solve acoustics radiation and scattering problems, very few investigations focus on the behavior of source distributions obtained as solutions, as well as on the general properties and restrictions these solutions must fulfill.
