<p>A system (100) for analyzing respiratory tract sounds in an individual (110). A plurality of N transducers (105) 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 (135) receives the signals P(xi,t) and determines an average acoustic energy P(x,t1,t2) at at least one position x over a time interval where P is determined in an algorithm involving at least one of the signals P(xi,t).</p> |
