Patent ID: 6887208

Claim:
A system for analyzing sounds in at least a portion of an individual's respiratory tract comprising: (a) a plurality of N transducers, each transducer configured to be fixed on a surface of the individual over the thorax, the ith transducer being fixed at a location x i and generating a signal P(x i , t) indicative of pressure waves at the location x i ; for i=1 to N; and (b) a processor configured to receive the signals P(x i ,t) and determine an average acoustic energy {tilde over (P)}(x, t 1 , t 2 ) at at least one position x over a time interval from a first time t 1 to a second time t 2 , {tilde over (P)} being determined in an algorithm involving at least one of the signals P(x i ,t).
