This paper describes a particle filter based sound source mapping system that builds 2D sound source maps from directional sound readings taken from a mobile robot. The method uses a sound source localization model that is represented by Gaussian distribution for both direction and distance. To do this, accurate directional localization of sound sources is required, and two key components have been...
This paper describes the arrangement optimization method of a microphone array for localizing and segmenting sound sources based on delay and sum beam forming (DSBF) method. For this purpose, two indexes are defined, 1) width of main lobe and 2) maximum sensitivity of side lobe. Then evaluation function that presents performance of microphone array using these indexes is proposed. Using proposed method,...
This paper describes a two-dimensional sound source localization method which uses the directional pattern of each microphone to perform acute beam forming in azimuth and elevation using a 32-channel distributed microphone array. The localization method is based on delay and sum beam forming (DSBF) and frequency band selection (FBS). The microphone arrangement is determined by simulation of the proposed...
The paper proposes multiple sound sources localization method using directional pattern of a microphone array. Directional localization is achieved by using delay and sum beam forming (DSBF) and proposed main-lobe canceling method (MLC) using microphone directional pattern. The system subtracts higher intensity sound sources by using the directional pattern of a microphone array at each frequency,...
