摘要： 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. 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 (2) 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.

摘要： The invention concerns a device for assistance in the analysis of adventitious sounds, such as wheezing or crackling sounds. The invention is characterised in that said adventitious sounds are located on time/frequency spectral representations and parameterised according to a set of coefficients characterising them. Said sets of coefficients are stored in a storage unit for establishing a database or compared to synthesized sounds, based on parameters retrieved from such a database.
