Sound detection system with notification based on spectral signatures
A recently granted patent (Publication Number: US11972772B2) discloses a system designed to detect and notify users of specific events based on sound signals. The system comprises a first processor that analyzes electrical signals associated with sounds and sends data signals to a second processor if the sound meets a predetermined threshold. This threshold is determined based on the comparison of electrical signals during an ambient noise period and can be related to sound amplitude or frequency. The second processor, upon receiving the data signal, sends notifications indicative of the detected event, such as a doorbell ring or a smoke alarm, to the user via email or other devices.
Furthermore, the patent includes methods and devices implementing the sound detection system. The method involves receiving an electrical signal representing a sound, analyzing it against the threshold criteria, and sending data signals to the second processor for event detection. The device, equipped with processors and memory, operates similarly by sending data signals based on sound analysis to detect specific events. The system can identify various sounds like glass breaking or water flowing, and the second processor correlates the data signal with reference signals associated with different events. Overall, the patent aims to provide a reliable and efficient system for detecting and notifying users of specific sounds or events in their surroundings, enhancing safety and security measures.
