Physiological acoustic monitoring system

1. An acoustic monitoring system comprising:

first acoustic front-end circuitry that receives an acoustic sensor signal responsive to body sounds in a person;

a first signal path from the first acoustic front-end circuitry to an audio transducer;

a second signal path from the first acoustic front-end circuitry to an acoustic data processor via an analog-to-digital converter;

the audio transducer providing continuous audio of the body sounds; and

the acoustic data processor providing audio of the body sounds upon user demand.

2. The acoustic monitoring system according to claim 1 further comprising:

second acoustic front-end circuitry that receives a second acoustic sensor signal responsive to body sounds in a person;

a third signal path from the second acoustic front-end circuitry to a parameter processor via the analog-to-digital converter; and

the parameter processor deriving a physiological measurement responsive to the body sounds.

3. The acoustic monitoring system according to claim 2 further comprising:

a fourth signal path from the second acoustic front-end circuitry to the acoustic data processor via the analog-to-digital converter; and

the acoustic data processor providing a stereo audio output of the body sounds.

4. The acoustic monitoring system according to claim 3 further comprising:

a communications link to a remote site via a network;

a trigger responsive to the physiological measurement;

a notification transmitted over the communications link according to the trigger; and

the notification alerting an individual at the remote site of the physiological measurement and allowing the individual to request the body sounds be downloaded to the individual via the communications link.

5. The acoustic monitoring system according to claim 4 further comprising:

optical front-end circuitry that receives an optical signal responsive to pulsatile blood flow at a tissue site on the person;

the parameter processor deriving a second physiological measurement responsive to the pulsatile blood flow; and

the trigger responsive to a combination of the physiological measurement and the second physiological measurement.

6. The acoustic monitoring system according to claim 5 further comprising:

a plurality of acoustic filters implemented in the acoustic data processor;

the filters defining a plurality of audio bandwidths;

a plurality of controls in communications with the acoustic data processor;

the controls configured to adjust the audio bandwidths; and

the stereo audio output adjusted by the controls so as to emphasize at least one of the audio bandwidths and de-emphasize at least one other of the audio bandwidths so that a user of the controls can focus on a particular aspect of the stereo body sound output.

7. The acoustic monitoring system according to claim 6 further comprising a display that is responsive in real-time to the stereo audio output.
