Abstract[English]
The invention discloses a method for low-delay signal processing in a hearing in- strument (1), wherein a first input signal (E1) is generated from an environment sound (4) by means of a first input transducer (M1) of the hearing instrument (1), wherein a digital first intermediate signal (x1) is generated from the first input sig- nal (E1), said first intermediate signal (x1) having a first sample rate (fS,1), wherein in an analysis path (20), a decimation (24) is applied to the first intermediate signal (x1), resulting in a first decimated signal (d1) having a second sample rate (fS,2) smaller than the first sample rate (fS,1), and by means of a signal analysis of the first decimated signal (d1), first filter coefficients (c1j) of a signal processing filter (16) for the first intermediate signal (x1) are calculated, wherein in a processing path (10), the signal processing filter using (16) the first filter coefficients (c1j) is applied to the first intermediate signal (x1) at the first sample rate (fS,1), generating a first processed signal (y1), and wherein a first output signal (A1) of the hearing instrument (1) is derived from the first processed signal (y1).[French]
L'invention divulgue un procédé de traitement de signal à faible retard dans un instrument auditif (1), un premier signal d'entrée (E1) étant généré à partir d'un son d'environnement (4) au moyen d'un premier transducteur d'entrée (M1) de l'instrument auditif (1), un premier signal intermédiaire numérique (x1) étant généré à partir du premier signal d'entrée (E1), ledit premier signal intermédiaire (x1) présentant un premier taux d'échantillonnage (fS, 1), dans un trajet d'analyse (20), une décimation (24) étant appliquée au premier signal intermédiaire (x1), ce qui permet d'obtenir un premier signal décimé (d1) présentant un second taux d'échantillonnage (fS, 2) inférieur au premier taux d'échantillonnage (fS, 1), et au moyen d'une analyse de signal du premier signal décimé (d1), des premiers coefficients de filtre (c1j) d'un filtre de traitement de signal (16) pour le premier signal intermédiaire (x1) étant calculés, dans un trajet de traitement (10), le filtre de traitement de signal utilisant (16) les premiers coefficients de filtre (c1j) étant appliqués au premier signal intermédiaire (x1) au niveau du premier taux d'échantillonnage (fS, 1), générant un premier signal traité (y1), et un premier signal de sortie (A1) de l'instrument auditif (1) étant dérivé du premier signal traité (y1).
