Detection and classification of abnormal sounds
First Claim
1. An audio surveillance system, comprising:
- a plurality of nodes, wherein each node includes a microphone configured to detect sound and a speaker configured to provide sound; and
a control unit configured to;
receive a plurality of inputs from the plurality of nodes, wherein the plurality of inputs are based on a detected sound;
determine a location of the source of the detected sound based on the plurality of inputs;
classify the detected sound according to predefined alert conditions and based on the location of the source of the detected sound;
provide an alert to a monitoring device regarding the detected sound based on the classification of the detected sound; and
control at least one node from the plurality of nodes to provide an audio response to the detected sound.

Abstract
An audio surveillance system includes a plurality of nodes and each node includes a microphone, a speaker, and a control unit. The microphone is configured to detect sound and the speaker is configured to provide sound. The control unit is configured to receive a plurality of inputs from the plurality of nodes and the plurality of inputs are based on a detected sound; determine a location of the source of the detected sound based on the plurality of inputs; classify the detected sound according to predefined alert conditions and based on the location of the source of the detected sound; provide an alert to a monitoring device regarding the detected sound based on the classification of the detected sound; and control at least one node from the plurality of nodes to provide an audio response to the detected sound.

27. A method for detecting and classifying sounds, comprising:
-
receiving, by a control unit, a plurality of inputs from a plurality of nodes, wherein the plurality of inputs are based on at least one of a detected sound and a captured image; determining, by the control unit, a location of the source of the detected sound based on at least one of the detected sound and the captured image; classifying, by the control unit, the detected sound according to predefined alert conditions and based on the location of the source of the detected sound; providing, by the control unit, an alert to a monitoring device regarding the detected sound based on the classification of the detected sound; and controlling, by the control unit, at least on node from the plurality of nodes to provide an audio response to the detected sound. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
