초록 ▼

A system for suppressing the effects of undesirable noise from an annoying noise source contains a plurality of transformation sounds which, when combined with the noise form a sound that is pleasing to the ear. The transformation sounds are stored in the digital memory of the system or on a CD-ROM. The incident noise is detected and converted to signals which are dynamically analyzed, filtered and monitored to control the transformation sound selection process. The transformation sounds are modulated by a filtered signal derived from these noise signals that tracks the average energy in the noise. The transformation sounds include a primary transformation sound that is selected substantially continuously. The transformation sounds include also secondary transformation sounds that are selected for combination with the noise in periods when the primary transformation sound does not completely suppress the undesirable effects of the noise, and when the primary transformation sound is decreasing in volume. The system is especially effective in abating the traffic noise from freeways at nearby locations.

대표청구항 ▼

[ What is claimed is:] [1.] A system for suppressing the undesirable effects of a noise source by transforming the noise emitted by the source into replacement sounds in which said effects are alleviated, said system comprising:detecting means for detecting the noise emitted by said noise source and producing noise signals in response thereto;storage means for storing a plurality of signals to generate transformation sounds which, when combined with the noise emitted by said noise source, produce replacement sounds in which said effects are alleviated;processor means communicative with said detecting means and said storage means, said processor means receiving said noise signals from said detecting means and dynamically monitoring said noise signals, said processor means further selecting and receiving transformation sound signals from said storage means in response to said noise signals such that the combination of said noise and the transformation sounds generated by said selected transformation sound signals produces replacement sounds in which said effects are alleviated; andloudspeaker means for emitting said transformation sounds to combine said sounds with said noise, said loudspeaker means being communicative with said processor means, such that said processor means controls said loudspeaker means to cause said transformation sounds to be emitted and combined with said noise.
