Method and system for quantitation of respiratory tract sounds

A system for making a differential diagnosis between two respiratory tract disorders, comprising:

• (a) an integer N of transducers, each transducer configured to be fixed on a surface of the individual over the thorax, the ith transducer being fixed at a location xi and generating a signal Z(xi,t) indicative of pressure waves at the location xi;
• i=1 to N at times t during a predetermined time interval;
• (b) a processor configured to:
• receive the signals Z(xi,t) and to process the signals, wherein the processing comprises performing at least one event search;
• determine values of one or more initial event parameters;
• determine values of the one or more final event parameters and
• compare the values of the initial event parameters to the final event parameters, and to make differential diagnosis based on the comparison.
