Title
(EN) A STETHOSCOPE APPARATUS AND A METHOD OF PROCESSING BREATHING SOUNDS PRODUCED BY A SUBJECT
(FR) STÉTHOSCOPE ET PROCÉDÉ DE TRAITEMENT DE SONS DE RESPIRATION PRODUITS PAR UN SUJET
Abstract
(EN)
According to an aspect, there is provided a stethoscope apparatus stethoscope apparatus, the stethoscope apparatus comprising a sound sensor for measuring sounds produced by the breathing of a subject and for outputting a sound signal representing the measured breathing sounds; an antenna for receiving a modulated electromagnetic signal from the body, wherein the modulated electromagnetic signal is modulated by movement of air, fluid and/or tissue in the body; a processing unit that is configured to receive the sound signal from the sound sensor and the modulated electromagnetic signal from the antenna; and normalise the sound signal using the modulated electromagnetic signal.
(FR)
Selon un aspect, l'invention concerne un stéthoscope, le stéthoscope comprenant un capteur de son pour mesurer des sons produits par la respiration d'un sujet et pour émettre un signal sonore représentant les sons de respiration mesurés ; une antenne permettant de recevoir un signal électromagnétique modulé provenant du corps, le signal électromagnétique modulé étant modulé par déplacement d'air, de fluide et/ou de tissu dans le corps ; une unité de traitement qui est configurée pour recevoir le signal sonore provenant du capteur de son et le signal électromagnétique modulé provenant de l'antenne ; et normaliser le signal sonore à l'aide du signal électromagnétique modulé.
