Patent Images
1. An acoustic monitoring system comprising:
- an acoustic front-end that receives an acoustic sensor signal responsive to body sounds in a person;
a first signal path from the acoustic front-end to an audio transducer;
a second signal path from the acoustic front-end 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.

Abstract
An acoustic monitoring system has an acoustic front-end, a first signal path from the acoustic front-end directly to an audio transducer and a second signal path from the acoustic front-end to an acoustic data processor via an analog-to-digital converter. The acoustic front-end receives an acoustic sensor signal responsive to body sounds in a person. The audio transducer provides continuous audio of the body sounds. The acoustic data processor provides audio of the body sounds upon user demand.

8. An acoustic monitoring method comprising:
-
inputting a sensor signal responsive to body sounds of a living being; routing the sensor signal to an audio output device so as to enable a first user to listen to the body sounds; digitizing the sensor signal as acoustic data; transmitting the acoustic data to a remote device over a network; and reproducing the acoustic data on the remote device as audio so as to enable a second user to listen to the body sounds. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An acoustic monitor comprising:
-
an acoustic sensor having a piezoelectric assembly, an attachment assembly and a sensor cable; the attachment assembly retaining the piezoelectric assembly and one end of the sensor cable; the attachment assembly having an adhesive so as to removably attach the piezoelectric assembly to a tissue site; another end of the sensor cable in communications with a sensor interface so as to activate the piezoelectric assembly to be responsive to body sounds transmitted via the tissue site; and a wireless communications device responsive to the sensor interface so as to transmit the body sounds remotely. - View Dependent Claims (16, 17, 18)
