Bioacoustics is defined as the study of sounds produced by or affecting living organisms.1 When focusing on the sounds produced by the human body, a family of signals, namely the human bioacoustic signals or simply Bioacoustic Signals (BioS), could be formed. The BioS, being the audible outcome emitted from the human body, possess valuable diagnostic information regarding the functionality of the human organs involved in the sound production mechanisms. Proper extraction and use of this information can transform the art of BioS auscultation into a scientific discipline. This is achieved in part by the use of signal processing methods, which convert BioS from acoustic vibrations inside the human organism into graphs and parameters with diagnostic value. This diagnostic value is further revealed when advanced signal-processing techniques are employed in the analysis of BioS. In that way, novel diagnostic tools that objectively track the characteristics of the relevant pathology and assist the clinicians in everyday practice could be introduced.
