    Abstract: An image capture device detects a wind whistle using two or more microphones. The image capture device includes a processor that obtains microphone signals from the two or more microphones and determines coherence values between the microphone signals across a frequency band. The processor determines a coherence value for each frequency bin of the frequency band. Based on a detection of an elevated coherence value in a frequency bin, the processor determines the presence of a whistle. The processor attenuates the frequency bin based on a determination that the elevated coherence value is above a threshold.

    Abstract: A smart-home device may include a recording device configured to record sound during a first time interval and a memory device comprising a plurality of stored sound profiles. The smart-home device may also include a processing system configured to receive an environmental input, select a stored sound profile from the plurality of stored sound profiles based on the environmental input, and perform a noise-cancelation routine on the sound recorded during the first time interval. The stored sound profile may be used as an initial background noise profile for the noise-cancelation routine.

    Abstract: A method and system for reducing ambient noise distraction with an electronic personal display is disclosed. One example determines when the electronic personal display is in reader mode. In addition, ambient noise around the electronic personal display is also detected. Noise cancelling sound waves are generated at the electronic personal display for reducing ambient noise distraction. The noise cancelling sound waves are then output from at least one speaker coupled with the electronic personal display.

    Abstract: A method and system for deploying a display screen of an electronic personal display device. The device includes a processor, a display screen, and a memory storing instructions and a digital content item. The method comprises receiving an invocation of the digital content item stored in the memory, inferring that the digital content item is an e-book based on a metadata record of the e-book, the e-book having content displayable according to an ordered sequence of digitally constructed pages, detecting at least one ambient noise characteristic at the computing device, generating sound waves in cancellation of the at least one ambient noise characteristic, and outputting, from the computing device, the sound waves.

    Abstract: Edges β of a vibrator, that is, genesis locations of a bending moment of force caused by a vibrator, agree with positions α on a distribution of the bending moment of force caused by noise vibration of a panel, where the sign of the distribution of bending moment of force is reversed. As a result, control vibration approximate to the noise vibration can be excited. Accordingly, when the vibrator is fixed by agreeing the edges β of the vibrator with the positions α determined by noise frequency desired to be reduced, noise due to a target noise frequency can be effectively reduced.
