System for determining sound source
There is provided a system for determining a sound source and a method thereof. The system comprises: an audio sensor; a biosensor for measuring one or more biosignals of a subject; and a processing unit communicatively coupled with the audio sensor and the biosensor, the processing unit configured to perform operations comprising: obtaining audio data from the audio sensor and biosignal data from the biosensor, the audio data and the biosignal data being time-synced with each other, detecting, based on the audio data, a sound exceeding a threshold, and determining that the sound exceeding the threshold originates from the subject if the biosignal data indicates a change in the one or more biosignals at a corresponding time.
1. A system for determining a sound source, the system comprising:
an audio sensor;
a plurality of biosensors configured to measure one or more biosignals of, and configured to be associated with, a plurality of subjects; and
a processor communicatively coupled with the audio sensor and the biosensors, the processor being configured to perform operations comprising:
obtaining audio data from the audio sensor and biosignal data from the biosensors, the audio data and the biosignal data being time-synced with each other,
detecting, based on the audio data, a sound exceeding a threshold, and
determining that the sound exceeding the threshold originates from the subjects if the biosignal data indicates a change in the one or more biosignals at a corresponding time, and identifying the one of the subjects as generating sound based on the biosignal data obtained from the plurality of biosensors.
2. The system of claim 1 , wherein the processor is configured to perform further operations comprising generating for output an indication identifying a given subject, provided that sound exceeding the threshold is determined to originate from the given subject.
3. The system of claim 1 , wherein the processor is configured to perform further operations comprising:
determining, based on at least one predetermined criterion and the sound exceeding the threshold, a pain indicator for indicating subject experienced pain, and
generating output including the pain indicator.
4. The system of claim 3 , wherein the pain indicator is determined based on a predetermined correlation between at least one characteristic of sound and subject experienced pain.
5. The system of claim 4 , wherein the at least one characteristic of sound comprises sound pressure, the pain indicator being determined based on a predetermined correlation between the sound pressure and the subject experienced pain.
6. The system of claim 3 , wherein the determining of the pain indicator is further based on the biosignal data.
7. The system of claim 6 , wherein the determining of the pain indicator is further based on a predetermined correlation between an amount of change in the one or more biosignals and the subject experienced pain.
8. The system of claim 1 , wherein the biosignal data comprises heart rate data.
9. The system of claim 1 , wherein the biosignal data comprises heart rate variation data.
10. The system of claim 1 , wherein the biosignal data comprises respiration rate data.
11. The system of claim 1 , wherein the processor is configured to perform further operations comprising determining that the sound exceeding the threshold originates from the subjects only if the biosignal data indicates a change at the corresponding time in at least two of the following biosignals: heart rate, heart rate variation, and respiration rate.
12. The system of claim 1 , further comprising:
a body at least partially enclosing the audio sensor and the biosensor.
13. The system of claim 1 , further comprising:
a data store configured to store audio data and/or biosignal data; and
a server configured to obtain the stored data, the server comprising the processor.
14. A method for determining a sound source, the method comprising:
obtaining, by a processor, audio data from an audio sensor and biosignal data from a plurality of biosensors, the biosensors being configured to measure one or more biosignals of, and configured to be associated with, a plurality of subjects, the audio data and the biosignal data being time-synced with each other;
detecting, based on the audio data, a sound exceeding a threshold; and
determining that the sound exceeding the threshold originates from the subjects if the biosignal data indicates a change in one or more of the biosignals at a corresponding time, and identifying the one of the subjects as generating sound based on the biosignal data obtained from the plurality of biosensors.
15. The method of claim 14 , further comprising:
determining, based on at least one predetermined criterion and the sound exceeding the threshold, a pain indicator for indicating subject experienced pain; and
generating output including the pain indicator.
16. The method of claim 15 , wherein the pain indicator is determined based on a predetermined correlation between at least one characteristic of sound and subject experienced pain.
17. The method of claim 16 , wherein the at least one characteristic of sound comprises sound pressure, the pain indicator being determined based on a predetermined correlation between the sound pressure and the subject experienced pain.
18. The method of claim 15 , wherein the determining of the pain indicator is further based on the biosignal data.
19. The method of claim 17 , wherein the determining of the pain indicator is further based on a predetermined correlation between an amount of change in the one or more biosignals and the subject experienced pain.
20. The method of claim 14 , further comprising determining that the sound exceeding the threshold originates from the subjects only if the biosignal data indicates a change at the corresponding time in at least two of the following biosignals: heart rate, heart rate variation, and respiration rate.
