Title (EN) LOOP CIRCUIT
(FR) CIRCUIT DE BOUCLE
Abstract:
(EN) A driver for an induction loop hearing aid system comprises an input for receiving an input audio signal; a processor for processing the audio input signal to produce an output audio signal; and an output for outputting the output audio signal to an induction loop. The processor is operable in a setup process in which, utilising test signals at spaced apart frequencies, the transfer function of the processor is selected to provide substantially the same current in the loop in response to each test signal.
(FR) L'invention concerne un dispositif d'attaque pour un système d'appareil auditif à boucle d'induction, comprenant une entrée destinée à recevoir un signal audio d'entrée ; un processeur destiné à traiter le signal d'entrée audio afin de produire un signal de sortie audio ; et une sortie afin de délivrer le signal de sortie audio à une boucle d'induction. Le processeur peut fonctionner dans un processus de configuration selon lequel, à l'aide de signaux de test à des fréquences espacées, la fonction de transfert du processeur est sélectionnée pour fournir sensiblement le même courant dans la boucle en réponse à chaque signal de test.
