Reliability measure for sound source localization
In this paper, we propose a method of measuring the reliability of direction-of-arrival (DOA) estimation results. One idea for the reliability measure arises from a waterbed effect in DOA estimation. The reliability measure can be obtained from the difference between the maximum and minimum point of cross-correlation. If the calculated reliability measure has a lower value than a predefined thr...
متن کاملGaze as a Measure of Sound Source Localization
We present a study on utilizing eye movements for acoustic source localization tests. Test subjects had to indicate the presumed location of a hidden sound source with their head unconstrained by either fixating or additionally pointing with a laser pointer. Stimuli varied only in the horizontal plane from +45° (left) to -45° (right). Fixation error was always smaller than error in pointing and...
متن کاملBiomimetic Sound-Source Localization
Sound-source localization systems typically comprise free-field microphone arrays. In nature, directional acoustic sensing evolved to rely on diffraction about the head with only two ears. For localization, the brain uses the resultant frequency-dependent acoustic phase and intensity differences between the two ears. We conceive a biomimetic artificial head with microphones placed on its surfac...
متن کاملMulti-sources separation for sound source localization
Spatial localization given measurements of the sound field at a microphone array is a computationally challenging task. While big progress has been achieved in Azimuth localization, little attention has been paid to localization in distance. This paper presents a multi-sources localization model based on Time Delay of Arrival (TDOA) using only two microphones. The proposed method requires estim...
متن کاملSound Source Localization and Separation
People face the problem of sound source localization and separation in situations where they attempt to localize and focus on a source of sound among a dissonance of conversations and background noise. This paper synthesizes a sound source localization routine. We utilize a general source separation technique, Independent Component Analysis.. Particularly, basic ICA was applied to separate mixt...
