Abstract:
1. A sound recognition system, comprising: a sound input device; a processing device operatively coupled to said sound input device; and a display operatively coupled to said processing device; wherein: said processing device executes computer readable code to create a first visual representation of a first sound sensed by the sound input device for output on the display; wherein: said first visual representation is evaluated to determine whether a security breach has occurred; and wherein: said first visual representation is generated according to a method comprising the steps of: (a) placing twelve labels in a pattern of a circle, said twelve labels corresponding to twelve respective frequencies, such that moving clockwise or counter-clockwise between adjacent ones of said labels represents a first frequency interval; (b) identifying an occurrence of a first frequency within the first sound; (c) identifying an occurrence of a second frequency within the first sound; (d) identifying a first label corresponding to the first frequency; (e) identifying a second label corresponding to the second frequency; (f) creating a first line connecting the first label and the second label,
