Abstract
In accordance with an embodiment, a system for surveillance includes an audio signal analyzer, wherein the audio signal analyzer is configured to receive one or more audio microphone signals, where the audio signal analyzer is configured to determine a pattern matching result by determining whether the one or more microphone signals comprise at least one audio pattern of one or more predefined audio patterns; an air pressure change determiner, where the air pressure change determiner is configured to receive an air pressure change signal indicating an air pressure change; and an evaluator, wherein the evaluator is configured to indicate, depending on the pattern matching result and depending on the air pressure change, that a predefined event occurred.
Claims19
A system for surveillance, comprising:
- an audio signal analyzer comprising a first sensor device, wherein the audio signal analyzer is configured to receive one or more audio microphone signals at a first input, wherein the audio signal analyzer is configured to determine a pattern matching result by determining whether the one or more audio microphone signals comprise at least one audio pattern of one or more predefined audio patterns;
- an air pressure change determiner comprising a second sensor device different from the first sensor device, wherein the air pressure change determiner is configured to receive an air pressure change signal indicating an air pressure change at a second input distinct from the first input, and wherein the one or more audio microphone signals and the air pressure change signal comprise different signals respectively received by the first sensor device and the second sensor device;
- and
- an evaluator, wherein the evaluator is configured to indicate, depending on the pattern matching result and depending on the air pressure change, that a predefined event occurred,
- wherein the first sensor device comprises a microphone and the second sensor device comprises a barometric air pressure sensor.
A method for surveillance, comprising:
- receiving one or more audio microphone signals by a first sensor device;
- determining a pattern matching result by determining whether the one or more audio microphone signals comprise at least one audio pattern of one or more predefined audio patterns;
- receiving an air pressure change signal indicating an air pressure change by a second sensor device different from the first sensor device;
- or receiving an air pressure signal indicating a current air pressure by the second sensor device and determining the air pressure change from the air pressure signal indicating the current air pressure and from a previously received air pressure;
- and
- indicating, depending on the pattern matching result and depending on the air pressure change, that a predefined event occurred,
- wherein the one or more audio microphone signals and the air pressure change signal comprise different signals respectively received by the first sensor device and the second sensor device,
- wherein the first sensor device comprises a microphone and the second sensor device comprises a barometric air pressure sensor.
A system for surveillance, comprising:
- an audio signal analyzer comprising a microphone device, wherein the audio signal analyzer is configured to receive one or more audio microphone signals at a first input, wherein the audio signal analyzer is configured to determine a pattern matching result by determining whether the one or more audio microphone signals comprise at least one audio pattern of one or more predefined audio patterns;
- an air pressure analyzer configured to receive an air pressure signal from a barometric air pressure sensor different from the microphone device at a second input distinct from the first input, and configured to determine a pressure pattern matching from the received air pressure signal;
- and
- an evaluator, wherein the evaluator is configured to indicate, depending on the pattern matching result and depending on the determined pressure pattern, that a predefined event occurred.
