Abstract:
1. A system for analyzing sounds originating in at least a portion of an individual's cardiovascular system comprising: (One) N transducers, where N is an integer, each transducer configured to be fixed on a surface of the individual over the thorax, the ith transducer being fixed at a location x (Two) a processor configured to receive the signals P(x wherein respiratory tract sounds have been removed, and wherein the processor is further configured to determine an average acoustic energy {tilde over (P)} (x,t wherein the function {tilde over (P)} is determined at one or more locations x in an algorithm comprising: (One) determining an average acoustic energy {tilde over (P)} (x (Two) determining an average acoustic energy {tilde over (P)} (x,t
