Clustering Applied to the Acoustic Source Localization

open access: yesComputers & Mathematics with Applications, 2006
AbstractThis paper is concerned with a numerical scheme to the inverse source problem, called clustering. It is based on the theory of parallel optimization, and clusters several elements distributed in the area in concern by one point in time data, without prescribing the number of sources. Application to the acoustic source localization is discussed.

Acoustic source localization exploring theory and practice [PDF]

open access: yes, 2010
Over the past few decades, noise pollution became an important issue in modern society. This has led to an increased effort in the industry to reduce noise. Acoustic source localization methods determine the location and strength of the vibrations which are the cause of sound based onmeasurements of the sound field.
