description The invention provides a method and system for analyzing body sounds from one or more body organs. An array of transducers is fixed to the body surface over the organs from which body sounds are to be recorded. Analysis of the recorded sound signals includes dividing each signal into one or more time intervals and calculating an average of the signal in each time interval. A difference signal is calculated for each interval, where the difference signal is the difference of the recorded signal in the interval and the interval average. An energy assessment signal is then calculated in each interval using the difference signal. In an embodiment, the energy assessment signal is a standard deviation signal. The subject matter may be used to record and analyze cardiovascular sounds for diagnosing abnormal cardiovascular function, or for calculating an ejection fraction.
