An embodiment as described herein includes a microelectromechanical system (MEMS) with a first MEMS transducer element, a second MEMS transducer element, and a semiconductor substrate. The first and second MEMS transducer elements are disposed at a top surface of the semiconductor substrate and the semiconductor substrate includes a shared cavity acoustically coupled to the first and second MEMS transducer elements.

System and method for a mems transducer

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.

System and method for surveillance

In accordance with an embodiment, a system includes an audio signal analyzer configured to receive one or more audio microphone signals, and configured to determine a first pattern matching result by determining whether the one or more microphone signals include at least one audio pattern of one or more predefined audio patterns. Moreover, the system includes an air pressure signal analyzer configured to receive an air pressure change signal indicating an air pressure change, or configured to receive an air pressure signal indicating a current air pressure. The air pressure signal analyzer is configured to determine a second pattern matching result by determining whether the air pressure signal or the air pressure change signal includes at least one pressure sensor pattern. Furthermore, the system comprises an evaluator configured to indicate, depending on the first pattern matching result and depending second pattern matching result that a predefined event occurred.
