A Method for Source-Microphone Range Estimation in Reverberant Environments, Using an Array of Microphones of Unknown Relative Position
نویسندگان
چکیده
Estimating the range between an acoustic source and a microphone is a central problem in microphone-array processing. Although many approaches have been proposed in the literature, these tend to require knowledge of the relative microphone positions. We propose a range estimation method, for use in reverberant environments and where the relative positioning of the elements of a microphone-array is unknown. We demonstrate the effectiveness of this method under real, reverberant conditions.

A Method for Source-Microphone Range Estimation in Reverberant Environments Using Arrays of Unknown Geometry
This paper proposes a technique for determining the distance between a sound source and the microphones in an array. The proposed “Range-Finder” algorithm is robust in the presence of reverberation and, in contrast with previously published sourcelocalization techniques, does not require knowledge of the relative positions of the microphones. We discuss the factors affecting the accuracy of our...
متن کاملA microphone position calibration method in a reverberant environment for a randomly distributed array
A microphone position calibration method in a reverberant environment is investigated for randomly distributed large-size array in this paper. The microphone positions need to be known exactly in order to localize sound sources. Time delay estimation (TDE) is an important step in calibrating the microphone positions using a few calibrating sound sources for a randomly distributed array. However...

متن کاملSource Localisation Mapping using Weighted Interaural Cross-Correlation
Computational sound localisation using binaural microphones requires accurate Interaural Time Difference (ITD) estimation in order to infer an angle of incidence. The Phase Transform weighting function, used in generalized cross correlation calculations for microphone arrays is investigated here for application to ITD estimation in binaural head recordings. Empirical measurements using the meth...
متن کاملA Free-Source Method (FrSM) for Accurately and Quickly Calibrating a Large-Aperture Microphone Array
Large-aperture microphone arrays can be used to capture and enhance speech from individual talkers in noisy, multi-talker, and reverberant environments. An important factor for their use is array calibration. Due to the size and complexity of these arrays, direct-measuring techniques such as using a measuring tape or a laser-based tool are too cumbersome and time consuming. Previous methods tha...
