US Patent 6887208 Method and system for analyzing respiratory tract sounds

A method and system for analyzing respiratory tract sounds in an individual. A plurality of N transducers are fixed over the thorax. The ith transducer is fixed at a location xi, and generates a signal P(xi,t) indicative of pressure waves at the location xi, for i=1 to N. A processor receives the signals P(xi,t) and determines an average acoustic energy {tilde over (P)}(x,t1,t2) at at least one position x over a time interval where {tilde over (P)}is determined in an algorithm involving at least one of the signals P(xi,t).
