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 source-localization techniques, does not require k...
