Abstract

An acoustic monitoring system includes a portable acoustic detection device, a sound analysis device and a confidence level device. The portable acoustic detection device is capable of receiving sound at one or more locations near a sound-producing device. The sound analysis device receives the sound from the portable sound detection device, determines a diagnosis based on a comparison between the sound and pre-recorded sound data, and outputs the diagnosis to the portable acoustic detection device. The sound analysis device also determines a corrective action for inhibiting the sound, which is also output to the portable sound detection device. The confidence level device determines a confidence level of the diagnosis indicating a likelihood that the diagnosis is successfully diagnosed.

Claims

1. A method of monitoring acoustics produced by a sound-producing device, the method comprising:

receiving sound from a sound-producing device via a portable acoustic detection device;

communicating the sound to a sound analysis device via a data network and comparing the sound to pre-recorded sound data to determine at least one diagnosis of the sound-producing device;

determining at least one corrective action based on the at least one diagnosis;

determining a confidence level of the at least one diagnosis indicating a likelihood that the at least one diagnosis is successfully diagnosed;

increasing a particular confidence level of a respective diagnosis based on a comparison between the particular confidence level and a predetermined threshold value, the increase of the particular confidence level performed automatically in response to the particular confidence level being less than the predetermined threshold value, wherein the confidence-increasing action includes communicating with at least one of a technician and a social media network via the data network to receive updated corrected actions.

2. The method of claim 1, further comprising updating the confidence level of the at least one diagnosis in response to a result of the corrective action upon the sound-producing device.

3. The method of claim 1, further comprising outputting the at least one diagnosis to the portable acoustic detection device based on the confidence level.

4. The method of claim 1, further comprising inputting at least one input from a user of the portable acoustic detection device to identify the sound-producing device and displaying at least one of the diagnosis and the corrective action output from the sound analysis device via the portable acoustic diagnosis device, wherein the diagnosis is based on the at least one input.

5. The method of claim 1, wherein the receiving sound from a sound-producing device is performed using at least one of a portable terminal and a smartphone.

6. The method of 1, further comprising storing the pre-recorded sound data, and receiving at least one of externally pre-recorded sounds and technician corrected actions.

7. A method of detecting sound from a sound-producing device, the method comprising:

electrically communicating identification data that identifies the sound-producing device;

receiving locality information that indicates a least one location to position a portable acoustic detection device to receive sound produced by the sound-producing device based on the identification data;

receiving the sound at the at least one location indicated by the locality information;

comparing the sound to pre-stored sound data;

outputting a diagnosis and corrective action information to the portable acoustic detection device based on the comparing to inhibit the sound;

determining a confidence level indicating a likelihood of success of the at least one diagnosis; and

increasing a particular confidence level of a respective diagnosis based on a comparison between the particular confidence level and a predetermined threshold value, the increase of the particular confidence level performed automatically in response to the particular confidence level being less than the predetermined threshold value, wherein the confidence-increasing action includes communicating with at least one of a technician and a social media network via the data network to receive updated corrected actions.

8. The portable acoustic detection device of claim 7 further comprising:

displaying the diagnosis and corrective information.

9. The method of claim 8, further comprising updating the confidence level in response to a result of the corrective action taken upon the sound-producing device.

10. The method of claim 7, wherein the increasing the particular confidence level includes communicating with at least one of a technician and a social media network via the data network to receive updated corrected actions.

11. The method of claim 10, further comprising outputting the at least one diagnosis to the portable acoustic detection device based on the confidence level.

12. A method of analyzing sound produced by a sound-producing device, the method comprising:

receiving sound data received by a portable acoustic detection device via a data network, the sound data based on sound produced by the sound-producing device;

storing pre-stored sound data, diagnosis data corresponding to the pre-stored sound data, and corrective action data corresponding to the diagnosis data;

determining at least one diagnosis of the sound-producing device based on a comparison between the sound data and the pre-recorded sound data; and

determining at least one corrective action based on the at least one diagnosis;

determining a confidence level of the at least one diagnosis indicating a likelihood that the at least one diagnosis is successfully diagnosed; and

increasing a particular confidence level of a respective diagnosis based on a comparison between the particular confidence level and a predetermined threshold value, the increase of the particular confidence level performed automatically in response to the particular confidence level being less than the predetermined threshold value, wherein the confidence-increasing action includes communicating with at least one of a technician and a social media network via the data network to receive updated corrected actions.

13. The method of claim 12, further comprising outputting the at least one diagnosis to the portable acoustic detection device based on the confidence level, and displaying at least one diagnosis and a respective corrective action via the portable acoustic detection.

14. The method of claim 12, further comprising updating the confidence level in response to a result of the corrective action taken upon the sound-producing device.

15. The method of claim 14, wherein increasing the confidence level is performed in response to inhibiting the sound data by the corrective action and decreasing the confidence level in response to the sound being unaffected by the corrective action.
