Device for analyzing auscultation sounds, in particular respiratory sounds

Abstract

The invention concerns a device for analysing medical sounds, in particular respiratory sounds, comprising an input receiving a sound signal sampled in intensity levels each associated with a selected time, and storage means ( ) comprising a processing module for evaluating, in cooperation with computing means ( ), a set of transformed intensity levels, each associated with a predetermined sound frequency. It further comprises an output ( ) connected to the storage means ( ) for delivering each transformed intensity level in correspondence with an associated frequency, and means for representing ( ) intensity levels transformed on the basis of frequencies, to obtain a spectral representation of the auscultation sound. The invention is characterised in that the processing module is further capable of evaluating a set of transformed intensity levels for each selected time, and the storage means ( ) store each intensity level transformed on the basis of an associated frequency, and of a selected time, thereby providing a three-dimensional representation in time and in frequencies of the auscultation sound.
