Abstract
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.
