An Auditory System Modeling in Sound Source Localization
Sound localization of the auditory system is useful in the industrial and military applications such as game, sonar, sound quality measurement. Two main key features that the auditory system utilizes for sound source localization are interaural intensity differences (IID’s) and interaural time differences (ITD’s). Both become the cues for the estimation of the elevation and azimuth of the sound...
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 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...
متن کاملReflection-Aware Sound Source Localization
We present a novel, reflection-aware method for 3D sound localization in indoor environments. Unlike prior approaches, which are mainly based on continuous sound signals from a stationary source, our formulation is designed to localize the position instantaneously from signals within a single frame. We consider direct sound and indirect sound signals that reach the microphones after reflecting ...
متن کاملRole of auditory cortex in sound localization in the midsagittal plane.
Although the auditory cortex is known to be essential for normal sound localization in the horizontal plane, its contribution to vertical localization has not so far been examined. In this study, we measured the acuity with which ferrets could discriminate between two speakers in the midsagittal plane before and after silencing activity bilaterally in the primary auditory cortex (A1). This was ...
