Appl. No.:

13/618761

Assignee:

SIKORSKY AIRCRAFT CORPORATION - Stratford CT

International Classification:

G10K 11/16

US Classification:

381 716, 381 711

Abstract:

A noise-suppression assembly of a mechanical drive system having a rotational frequency includes an audio filter unit configured to receive a first audio signal and a timing signal of the mechanical drive system. The audio filter unit generates a noise-cancellation signal based on a frequency of the timing signal to suppress a noise generated by the mechanical drive system and to apply the noise-cancellation signal to the first audio signal to produce a filtered first audio signal. The frequency of the timing signal is based on the rotational frequency of the mechanical drive system.

International Classification:

G10K 11/178
G10L 21/0216

Abstract:

Embodiments of the present disclosure set forth a method of reducing noise in an audio signal. The method includes determining, based on sensor data acquired from a first set of sensors, a first position of a user in an environment. The method also includes acquiring, via the first set of sensors, one or more audio signals associated with sound in the environment and identifying one or more noise elements in the one or more audio signals. The method also includes generating a first directional audio signal based on the one or more noise elements. When the first directional audio signal is outputted by a first speaker, the first speaker produces a first acoustic field that attenuates the one or more noise elements at the first position.

Assignee:

Harman International Industries, Incorporated - Stamford CT

International Classification:

H04R 25/00

Abstract:

A system and method for customizing a hearing device to the purchased at the point of sale. The system has a user interface and a test hearing device having a plurality of biometric sensors arranged in a sensor array that contact a user for detecting data representative of an auditory brainstem response. The system creates a customized hearing algorithm using the collected data. The hearing device to be purchased is communicatively coupled to the user interface and the customized hearing algorithm is downloaded to the hearing device to be purchased.

Inventors:

- Stamford CT, US
Donald Joseph Butts - Westport CT, US

International Classification:

G10K 11/178

Abstract:

The various embodiments set forth an active noise cancellation system that includes a source separation algorithm. The source separation algorithm enables the identification of acoustic inputs from a particular sound source based on a reference signal generated with one or more microphones. Consequently, the identified acoustic inputs can be cancelled or damped in a targeted listening location via an acoustic correction signal, where the acoustic correction signal is generated based on a sound source separated from the reference signal. Advantageously, the reference signal can be generated with a microphone, even though such a reference signal may include a combination of multiple acoustic inputs. Thus, noise sources that cannot be individually measured, for example with an accelerometer mounted to a vibrating structure, can still be identified and actively cancelled.

Abstract:

The various embodiments set forth an apparatus comprising an earpiece, a sensor configured to measure an inherent attribute associated with a user, a wireless transceiver configured to communicate with a wireless access point of a wireless communication network, and a controller. The controller is configured to establish authenticated access to the wireless communication network based on the inherent attribute associated with the user. An advantage of the disclosed embodiment is that a hearable device can conveniently authenticate user access to a network with enhanced security, based on one or more inherence factors that are measured by the hearable device.

International Classification:

H03G 5/16
G06F 3/01
H04R 3/04

Abstract:

A technique for determining one or more equalization parameters includes acquiring, via one or more electrodes, auditory brainstem response (ABR) data associated with a first audio sample and determining, via a processor, one or more equalization parameters based on the ABR data. The technique further includes reproducing a second audio sample based on the one or more equalization parameters, acquiring, via the one or more electrodes, complex auditory brainstem response (cABR) data associated with the second audio sample, and comparing, via the processor, the cABR data to at least one representation of the second audio sample to determine at least one measure of similarity. The technique further includes modifying the one or more equalization parameters based on the at least one measure of similarity.

Abstract:

One embodiment of the present invention sets forth a technique for generating an augmented view of a location of interest for a user. The technique includes determining an image capture location based on the location of interest, and determining an image capture direction based on the image capture location. The technique further includes receiving an image associated with the image capture location and the image capture direction. The technique further includes processing the image based on a line of sight associated with a location of the user to generate a processed image and displaying the processed image to the user. Advantageously, the disclosed techniques enable a user to see through obstructions in the surrounding environment to view a location of interest.
