    摘要： This disclosure provides for an auditory modification apparatus to facilitate extraction of information from an auditory observation stream. The approach may be used to reveal features about the environment, or to simplify processing of the incoming audio stream. The apparatus acts on the incoming auditory stream by nature of its shape, and that shape either is passively static or actively manipulated. Preferably, the apparatus has given shape characteristics to reveal features of the environment, such as directionality of a noise, size of an enclosed space, or materials of its construction, that are not otherwise detectable or easy to process with conventional approaches. Further advantage exists in the notion of actively manipulating the shape of the apparatus in conjunction with its operation to facilitate information extraction in a dynamic manner.

    摘要： Even a small sound for which a change in a histogram is small can be accurately detected. A signal detection device includes signal input means for inputting signals acquired by a plurality of sensors, cross-correlation function calculation means for calculating cross-correlation functions for each predetermined number of samples, based on the signals, and background noise model derivation means for deriving a background noise model, based on the cross-correlation functions; and detection means for detecting a change in the signals, based on comparison of values of the cross-correlation functions with the background noise model.

    摘要： The present invention relates generally to a method and system for defining a reference sound position and producing an indicia proximate thereto in relation to one or more sound characteristics. The present invention, in one or more embodiments, provides for displaying a holographic image at a reference sound location which is determined in relation to the identification of one or more target sounds being associated with one or more identified sound characteristics. In other embodiments, the present invention provides for an indicia to appear to be interactive with a reference sound location and may be used in a variety of environments including but not limited to rock theatrics, homeland security and residential security.
