Title (EN) CALIBRATION AND STABILIZATION OF AN ACTIVE NOISE CANCELATION SYSTEM
(FR) CALIBRAGE ET STABILISATION D'UN SYSTÈME DE SUPPRESSION ACTIVE DU BRUIT
Abstract:
(EN) A method of calibrating an earphone may include: securing an ANC earphone to a calibration fixture, the calibration fixture including an ear model configured to support the ANC earphone, the ear model having an ear canal configured to anatomically resemble a human ear canal and a concha configured to anatomically resemble a human ear concha, the ear canal extending from the concha to an inner end of the ear canal; generating, with the ANC earphone, an audio signal based on a reference tone; determining a characteristic of the audio signal; comparing the characteristic of the audio signal to a previously determined reference characteristic; and adjusting a gain value of the ANC earphone based on the comparing. Additional methods and apparatus are also disclosed.
(FR) Cette invention concerne un procédé de calibrage d'une oreillette, comprenant éventuellement : la fixation d'une oreillette à suppression active du bruit sur un dispositif de calibrage, le dispositif de calibrage comprenant un modèle d'oreille conçu pour supporter l'oreillette à suppression active du bruit, le modèle d'oreille possédant un conduit auditif conçu pour ressembler anatomiquement à un conduit auditif humain et une conque configurée pour ressembler anatomiquement à une conque d'oreille humaine, le canal auditif s'étendant de la conque jusqu'à une extrémité interne du canal auditif ; la génération, au moyen de l'oreillette à suppression active du bruit, d'un signal audio basé sur une tonalité de référence ; la détermination d'une caractéristique du signal audio ; la comparaison de la caractéristique du signal audio avec une caractéristique de référence préalablement déterminée ; et l'ajustement d'une valeur de gain de l'oreillette à suppression active du bruit sur la base de la comparaison. L'invention concerne en outre des procédés et des appareils associés.
