Title
(EN) A HEARING INSTRUMENT WITH ADAPTIVE DIRECTIONAL SIGNAL PROCESSING
(FR) INSTRUMENT D'AUDITION AVEC TRAITEMENT DU SIGNAL DIRECTIONNEL ADAPTATIF
Abstract
(EN)
The present invention relates to a hearing instrument with at least two microphones for reception of sound and conversion of the received sound into corresponding electrical sound signals that are input to a signal processor, wherein the signal processor is adapted to process the electrical sound signals into a combined signal with a directivity pattern with at least one adaptive null direction ϑ and prevent the at least one null direction ϑ from entering a prohibited range of directions, wherein the prohibited range is a function of a parameter of the electrical sound signals.
(FR)
La présente invention concerne un instrument d'audition ayant au moins deux microphones pour recevoir le son et convertir le son reçu en signaux sonores électriques correspondants entrés dans un processeur du signal. Ce dernier peut traiter les signaux sonores électriques en un signal combiné dont le diagramme de directivité présente au moins une direction adaptative nulle (ϑ) et empêcher ladite direction nulle (ϑ) d'entrer dans une plage de direction interdite. La plage interdite est une fonction d'un paramètre des signaux sonores électriques.
