    摘要: A kit for attenuation of noise includes a noise source audio transducer, two ear pieces, and a control unit. The two ear pieces have respective resilient bodies that engage outer portions of ear canals of respective ears of a user while respective in-ear transducers of the two ear pieces are respectively positioned in inner portions of the ear canals. The respective in-ear transducers detect discrepancies (e.g., incomplete superpositioning) between the noise and the anti-noise. The respective in-ear transducers optionally detect respective secondary path effects in the ear canals. The noise source audio transducer detects noise generated by a noise source (e.g., snoring noise). The control unit configures an adaptive filter based at least in part on an error signal, and optionally based in part on secondary path effects. The control unit generates signals representative of anti-noise. The two ear pieces produce the anti-noise responsive to the signals. The two ear pieces produce masking noise with sound level that varies in direct correlation with sound level of the noise generated by the noise source.

    摘要: A mobile communication device having an acoustic divider for minimizing acoustic coupling is disclosed. The mobile communication device includes a housing having an outer surface and internal sidewalls. The outer surface and internal sidewalls define a void disposed at and below the outer surface of the housing. The mobile communication device includes a receiver disposed within the housing and below a first portion of the void, and a microphone disposed within the housing and below a second portion of the void. An acoustic divider is disposed within the void and laterally disposed between the receiver and the microphone. The acoustic divider acoustically isolates the first and second portions of the void, thereby minimizing acoustic coupling between the receiver and the microphone.

    摘要: A noise reduction device includes a plurality of noise microphones, noise controller, and control speakers. Noise controller generates a control-sound signal to reduce a noise, at a control center of a control space, with the noise being detected by the plurality of noise microphones. Noise microphone disposed at a shorter distance from the control center than distance “d” indicated by Relational Expression (1) is smaller in number than noise microphones disposed at longer distances than distance “d” where “λ” is a wavelength corresponding to control upper-limit frequency “f” in noise microphones, “d0” is a distance from the control center to control speakers, “t” is a control delay time in control speakers, and “v” is a sound speed. d=d0+t×v−λ/2  (1)

    摘要: A method of active noise cancellation and an associated system for cancelling noise within an enclosed space are described. The method involves detecting acoustic noise outside of the enclosed space. The method then involves generating a noise cancellation signal outside of the enclosed space, such that the acoustic noise is cancelled prior to the acoustic noise entering the enclosed space.
