Abstract
Methods and systems for determining physiological parameters from body sounds obtained from a person'"'"'s ear. In various exemplary embodiment, the system includes an earplug housing; a sensing element disposed within a portion of the earplug housing; an acoustic shield coupled to the earplug housing, the acoustic shield reducing or eliminating extracorporeal sounds; and a preamplification circuit electrically coupled to the sensing element. In various exemplary embodiments, the system is operable to determine motion and/or vibration of the external acoustic meatus or the tympanic membrane of the ear due to internally generated body sounds.

29. A method for determining cardiovascular parameters of a person, the method comprising:
-
placing a sensing device within a person'"'"'s ear;
placing a blood-pressure waveform sensor at a location distal to the heart;
obtaining a first set of waveforms from the sensing device;
obtaining a second set of waveforms from the blood-pressure waveform sensor;
performing a signal processing or conditioning operation using the first and second sets of waveforms;
determining a time delay between the dicrotic notch component of the conditioned blood-pressure waveform signal and the S2 component of the conditioned ear sensor signal;
determining a blood pressure pulse transit time value by adding S2D, representing a time delay between a person'"'"'s heart valve closure time and an arrival time of the S2 signal at the first distal location, to the time delay between the dicrotic notch signal and the S2 signal; and
determining cardiovascular parameters of a person using the determined blood pressure pulse transit time and at least one physical parameter representative of a arterial distance between a location of aortic valve of the heart and a location of the blood-pressure waveform sensor. - View Dependent Claims (30, 31, 32)
