Effect of source spectrum on sound localization in an everyday reverberant room

Effect of source spectrum on sound localization in an everyday reverberant room.

Two experiments explored how frequency content impacts sound localization for sounds containing reverberant energy. Virtual sound sources from thirteen lateral angles and four distances were simulated in the frontal horizontal plane using binaural room impulse responses measured in an everyday office. Experiment 1 compared localization judgments for one-octave-wide noise centered at either 750 ...

Sound source localization in reverberant environments using an outlier elimination algorithm

Di erences in arrival times of acoustic waves at multiple sensors permit the computation of source location. The computation depends upon delay estimation between sensor pairs. In severe acoustic environments, the estimates are degraded by reverberation and interfering noise, and some estimates are poor, constituting outlier. This report describes a computational method for outlier elimination ...

Binaural Sound Source Localization in Noisy Reverberant Environments Based on Equalization-Cancellation Theory

Experimental 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 ...

Effect of Reflectors on Sound-Source Localization with Two Microphones*

The localization performance of the source localization algorithms degrades in reverberant conditions. The performance of one such localization algorithm, the localization–extraction (LE) algorithm, was measured systematically as a function of the number of reflecting surfaces in a cubical enclosure. Localization was qualitatively measured using a localization plot and quantized using two objec...
