  • Device for analyzing auscultation sounds, in particular respiratory sounds
    Patent number: 6699204
    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 (2, 4, 5) comprising a processing module for evaluating, in cooperation with computing means (3), a set of transformed intensity levels, each associated with a predetermined sound frequency. It further comprises an output (26) connected to the storage means (2) for delivering each transformed intensity level in correspondence with an associated frequency, and means for representing (6, 90, 91) intensity levels transformed on the basis of frequencies, to obtain a spectral representation of the auscultation sound.
