Claim 17:
18. A method of processing acoustic heart signal data, the method comprising:
capturing time series acoustic heart signal data from a patient, the time series acoustic heart signal data representing the sound of the patient's heart;
extracting acoustic features from the time series acoustic heart signal data to provide time series acoustic feature data;
classifying the time series acoustic feature data using each of at least two heart models, a first heart model representing a normal heart and a second heart model represents a heart with a heart murmur; and
determining which of the first model and the second model best fits the acoustic heart signal data; and
outputting data indicating whether or not the patient's heart has a heart murmur when the second heart model fits the acoustic heart signal data better than the first model.
