Patent Images
1. 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;
generating a request in response to a second user actuating a button on a remote device to listen-on-demand;
receiving the request from the remote device to receive the body sounds;
transmitting the acoustic data to the remote device over a network; and
reproducing the acoustic data on the remote device as audio so as to enable the second user to listen to the body sounds.

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.

7. An acoustic monitoring method comprising:
-
receiving a first acoustic physiological signal from a first acoustic sensor coupled with a medical patient; detecting, with a processor, a feature corresponding to a physiological sound in the first acoustic physiological signal; selecting a tag from a set of predetermined tags representing physiological sounds at least partially based on the detected feature; and outputting the tag in lieu of the audio corresponding to the feature. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A system for acoustic monitoring, the system comprising:
a processor of a first device, the processor configured to; receive a first acoustic physiological signal from a first acoustic sensor coupled with a medical patient; detect a waveform envelope representing acoustic-related physiological phenomenon in the first acoustic physiological signal; transform the detected waveform envelope into data representing an acoustic-related physiological phenomenon; and transmit said data to a second device in lieu of the first acoustic physiological signal; receive a second acoustic physiological signal from a second acoustic sensor coupled with the medical patient; compare the first and the second acoustic physiological signal to determine a relative time of arrival of tracheal sounds; and generate frequency shifts based on the relative time of arrival of the tracheal sounds to distinguish inhalation and exhalation. - View Dependent Claims (18, 19, 20)
