Patent

CA 2404071

A method is provided for positioning the individual elements of a microphone arrangement including at least two such elements. The spacing among the microphone elements supports the generation of numerous combinations of the signal of interest and a sum of interfering sources. Use of the microphone element placement method leads to the formation of many types of microphone arrangements, comprising at least two microphone elements, and provides the input data to signal processing system for sound discrimination. Many examples of these microphone arrangements are provided, some of which are integrated with everyday objects. Also, enhancements and extensions are provided for a signal separation-based processing system for sound discrimination, which uses the microphone arrangements as the sensory front end.

L'invention concerne un procédé destiné à positionner des éléments individuels d'un agencement de microphone comprenant au moins deux desdits éléments. L'espacement entre les éléments de microphone supporte la génération de nombreuses combinaisons du signal d'intérêt et d'une somme de sources d'interférence. L'utilisation du procédé de placement de l'élément de microphone conduit à la formation de nombreux types d'agencements de microphone, comprenant au moins deux éléments de microphone, et confère les données d'entrée au système de traitement de signal destiné à une discrimination auditive. De nombreux exemples de ces agencements de microphone sont présentés, certains étant intégrés à des objets de tous les jours. Des améliorations et des extensions ont été effectuées pour un signal de séparation fondé sur le système de traitement destiné à la discrimination auditive, lequel utilise les agencements de microphone en tant que extrémité avant sensorielle.
