Patent

CA 2432751

A method of processing the sound associated with alarm events is disclosed. It is based on a transducer that converts the energy from acoustic to electrical form, a sampling device that converts it from continuous analog to discrete digital format, a memory that stores the compressed version of the event to be detected and an algorithm that compares the digital signature of the stored events with the digital signature of the event under development. When the result of the comparison as a matching, a triggering notification signal is generated. It is essential for this invention that the events that are stored in a compressed form into the memory can be specified by the user through a system training procedure during which the sound that is desired to be detected is processed by the system implementing this invention, and stored in the form of a digital signature.
