Configuration for phonography cardio heart monitoring
First Claim
1. A method of monitoring first and second acoustic signals generated by a subject, the method comprising:
- adhering at least one acoustic transducer to an epidermis of the subject, the acoustic transducer configured to be acoustically coupled directly to the epidermis of the subject via an adhesive layer;
receiving from said at least one acoustic transducer at least one electrical signal representative of said first and second acoustic signals generated by the subject;
digitally filtering said at least one electrical signal to distinguish a first set of frequencies associated with the first acoustic signal from a second set of frequencies associated with the second acoustic signal; and
obtaining an electrical signal based on said first set of frequencies, said electrical signal representative of the first acoustic signal.

Abstract
A method of acoustic monitoring includes transducing acoustic energy from a first acoustic transducer attached to a first location on a patient the acoustic energy from the first transducer, comprising desired acoustic energy to be monitored and interfering acoustic energy and transducing acoustic energy from a second acoustic transducer, attached to a second, different location on a patient, the acoustic energy from the second transducer, comprising desired acoustic energy to be monitored and interfering acoustic energy. The method also includes converting the acoustic energy sensed at the first and second locations into first and second electrical signals and processing the first and second electrical signals to digitally remove interfering acoustic energy present in the second signal to provide an electrical signal representative of the acoustic signal that is being monitored.
