Abstract

Casque audio à réducteur de bruit Le casque (10) comporte : - un transducteur (16) (12) ; - une chaine de traitement anti-bruit (30, 40) comportant : - un microphone (31, 41) ; - un filtre de traitement anti-bruit (34, 44) qui comporte en série : - un filtre de stabilisation (34A, 44A) dont la fonction de transfert est égale sensiblement à l’inverse de la fonction de transfert du chemin secondaire traité, et - un filtre d’annulation de bruit (34B, 44B) dont la fonction de transfert est une fonction de transfert d’annulation du bruit. Le chemin secondaire est formé entre le transducteur (16) et le tympan, et la fonction de transfert du chemin secondaire traité est la fonction de transfert du chemin secondaire affectée des fonctions de transfert des composants assurant le traitement, à l’exception du filtre de traitement (34, 44).
