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. An acoustic monitoring system, comprising:

a portable acoustic detection device configured to receive sound from a sound-producing device;

a sound analysis device in electrical communication with the portable acoustic detection device via a data network, the sound analysis device configured to determine at least one diagnosis of the sound-producing device based on a comparison between the sound and pre-recorded sound data, and to determine at least one corrective action based on the at least one diagnosis; and

a confidence level device in electrical communication with the portable acoustic detection device and the sound analysis device, the confidence level device configured to determine a confidence level of the at least one diagnosis indicating a likelihood that the at least one diagnosis is successfully diagnosed,

wherein the confidence level device updates the confidence level of the at least one diagnosis in response to a result of the corrective action upon the sound-producing device.

2. The acoustic monitoring system of claim 1, wherein the confidence level module performs a confidence-increasing action that increases a particular confidence level of a respective diagnosis based on a comparison between the particular confidence level and a predetermined threshold value.

3. The acoustic monitoring system of claim 2, wherein the confidence-increasing action is 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.

4. The acoustic monitoring system of claim 3, wherein the diagnosis module outputs the at least one diagnosis to the portable acoustic detection device based on the confidence level.

5. The acoustic monitoring system of claim 1, wherein the portable acoustic detection device further comprises a user interface configured to receive at least one input from a user to identify the sound-producing device and to display at least one of the diagnosis and the corrective action output from the sound analysis device, wherein the diagnosis is based on the at least one input.

6. The acoustic diagnosis system of claim 1, wherein the portable acoustic detection device includes at least one of a portable terminal and a smartphone.

7. The acoustic monitoring system of claim 1, further comprising:

a sound database in electrical communication with the sound analysis device, the sound database configured to store the pre-recorded sound data, and to receive at least one of externally pre-recorded sounds and technician corrected actions.

8. A portable acoustic detection device, comprising:

a sensor configured to receive sound from a sound-producing device;

a wireless communication module configured to electrically communicate with a sound database that stores pre-stored sound data, and to transmit identification data that identifies the sound-producing device;

a sound application module configured to output locality information that indicates a least one location at which the portable acoustic detection device is positioned to receive the sound, and to output a diagnosis and corrective action information to inhibit the sound based on a comparison between the sound and the pre-stored sound data;

a user interface configured to display the diagnosis and corrective action information;

a confidence level module in electrical communication with the sound application module and the sound data, the confidence level module configured to determine a confidence level indicating a likelihood of success of the at least one diagnosis, the confidence level module configured to update the confidence level in response to a result of the corrective action taken upon the sound-producing device, and configured to perform a confidence-increasing action that increases a particular confidence level of a respective diagnosis based on a comparison between the particular confidence level and a predetermined threshold value.

9. The portable acoustic detection device of claim 8, wherein the confidence-increasing action is performed automatically in response to the particular confidence level being less than the predetermined threshold value.

10. The portable acoustic detection device of claim 9, 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, wherein the diagnosis module outputs the at least one diagnosis to the portable acoustic detection device based on the confidence level.

11. The portable acoustic detection device of claim 10, wherein the diagnosis module outputs a plurality of diagnoses that are prioritized based on respective confidence levels.

12. An acoustic analysis device, comprising:

a wireless communication module that electrically communicates with a portable acoustic detection device via a data network to receive sound data that is based on sound produced by a sound-producing device;

a sound database that stores pre-stored sound data, diagnosis data corresponding to the pre-stored sound data, and corrective action data corresponding to the diagnosis data;

a diagnosis module to determine at least one diagnosis of the sound-producing device based on a comparison between the sound data and the pre-recorded sound data, and to determine at least one corrective action based on the at least one diagnosis;

a confidence level module in electrical communication with the diagnosis module to determine a confidence level of the at least one diagnosis indicating a likelihood that the at least one diagnosis is successfully diagnosed, the confidence level module configured to update the confidence level in response to a result of the corrective action taken upon the sound-producing device.

13. The acoustic analysis device of claim 12, wherein the diagnosis module outputs the at least one diagnosis to the portable acoustic detection device based on the confidence level, and wherein the at least one diagnosis and a respective corrective action is output to the portable acoustic detection device for display.

14. The acoustic analysis device of claim 12, wherein the confidence level module increases the confidence level in response to the corrective action inhibiting the sound data and decreases the confidence level in response to the sound being unaffected by the corrective action.
