Acoustic Source Localization Based on Beamforming
نویسندگان
چکیده
Sound sources can be localized and analysed using phased microphone arrays.Beamforming is a method for processing microphone array data to produce images that represent the distribution of the acoustic source strength.It is an imaging technique that applies to continuous or discrete source distribution.A microphone array can be designed to be more sensitive to the sound coming from one or more specific directions than to sound coming from other directions.Different array types can be used depending on the equipment available, on other constraints of the experiment on the desired spatial resolution and dynamic range of the sound source maps. To improve beamforming recognition possibilities it is necessary to learn how to handle these algorithms correctly and how to set their parameters. Key-Words: -Acoustic signal, Array of microphones, Beamforming, Sound recognition, Sound propagation, Sound sources localization

Combination of Beamforming and Synchronization Methods for Epileptic Source Localization, using Simulated EEG Signals
Localization of sources in patients with focal seizure has recently attracted many attentions. In the severe cases of focal seizure, there is a possibility of doing neurosurgery operation to remove the defected tissue. The prosperity of this heavy operation completely depends on the accuracy of source localization. To increase this accuracy, this paper presents a new weighted beamforming method...
متن کاملExperimental comparison of particle filtering algorithms for acoustic source localization in a reverberant room
Traditional acoustic source localization techniques attempt to determine the current location of an acoustic source from data obtained at an array of sensors during the current time only. Recently, state-space methods have been proposed that use particle filters to perform recursive estimation of the current source location using all previous data. In this paper we present an overview of these ...
متن کاملA novel acoustic emission beamforming method with two uniform linear arrays on plate-like structures.
A novel acoustic emission (AE) source localization approach based on beamforming with two uniform linear arrays is proposed, which can localize acoustic sources without accurate velocity, and is particularly suited for plate-like structures. Two uniform line arrays are distributed in the x-axis direction and y-axis direction. The accurate x and y coordinates of AE source are determined by the t...
