Embodiment Construction

[0028] figure 1 A stethoscope according to one embodiment of the invention is shown. The stethoscope 1 comprises a chest piece 20 , a control device 30 and a connector 10 for connecting the chest piece 20 to the control device 30 . The stethoscope 1 may also include an earphone 40 connected to the chest piece 20 via the control device 30 and the connector 10 .

[0029] figure 2 shows the basis figure 1 The chest piece 20 of one embodiment of the stethoscope 1 . The chest piece 20 includes a primary sound sensor 24 ( figure 2 Also shown as M0), the first navigation sound sensor 21 ( figure 2 Also shown as M1), the second navigator sound sensor 22 ( figure 2 Also shown as M2) and the third navigator sound sensor 23 ( figure 2 also shown as M3). The navigation sound sensors 21-23 enclose the main sound sensor 24 therein. Preferably, the main sound sensor 24 is located at the center of the chest piece 20, the distance from the center of the main sound sensor 24 to ea...

Abstract

The invention relates to a method and system for locating a sound source. The system comprises: - a receiving unit (311) for receiving navigating sound signals from at least two navigating sound sensors (21, 22, 23), and receiving a selection instruction comprising a signal segment type corresponding to the sound source, wherein the at least two navigating sound sensors are received in a chest-piece (20), - a selecting unit (312) for selecting a segment from each navigating sound signal according to the signal segment type, - a calculating unit (313) for calculating a difference between the segments selected from the navigating sound signal, and - a generating unit (314) for generating a moving indication signal for guiding moving the chest-piece (20) to the sound source according to the difference.

Description

technical field [0001] The present invention relates to methods and systems for processing sound signals, in particular to methods and systems for localizing sound sources by processing sound signals. Background technique [0002] The stethoscope is a very common diagnostic device used in hospitals and clinics. In the past, many new technologies have been added to stethoscopes to make auscultation easier and more reliable. New technologies added include ambient noise cancellation, automatic heart rate counting, automatic phonocardiogram (PCG) recording and analysis, and more. [0003] The internal sounds of the body can be produced by different organs, and even different parts of the organs, which means that internal sounds are caused by different parts of the body. Take heart sounds as an example: mitral and tricuspid valves cause heart sound S1; aortic and pulmonary valves cause heart sound S2; and heart murmurs can originate from valves, chambers, and even vessels. Typ...
