  • Patent number: 10397711
    Abstract: The present disclosure relates in a first aspect to a method of determining an objective perceptual quantity of a noisy speech signal using directional sound information. The method comprises steps of applying a noisy speech signal comprising a mixture of target speech and interfering noise to a first hearing instrument with an adjustable microphone arrangement and controlling the adjustable microphone arrangement to produce first and second directivity patterns exhibiting first and second directivity indexes, respectively, wherein said second directivity index is smaller than the first directivity index at one or more reference frequencies. First and second noisy speech segments are recorded from the adjustable microphone arrangement using the first and second directivity patterns, respectively, and at least one value of the objective perceptual quantity of the noisy speech signal is determined by comparing the first noisy speech segment and the second noisy speech segment.

  • Patent number: 10397715
    Abstract: A method performed by a device includes generating a first signal in accordance with a first set of one or more operational settings, and determining whether the signal has an acceptable data integrity. If the device determines that the signal has an acceptable data integrity, the method includes maintaining a configuration of the device with the first set of one or more operational settings. If the device determines that the signal does not have an acceptable data integrity, then the method includes automatically configuring the device with a second set of one or more operational settings. The configuration of the device ith the first set of one or more operational settings is associated with greater power efficiency than the configuration of the device with the second set of one or more operational settings.

  • Patent number: 10362399
    Abstract: Some embodiments of the disclosure provide systems and methods of detecting headphone orientation. The systems and methods described herein may be used, for example, to determine which ear cup of a pair of headphones is positioned on which ear of a user. By making this determination, stereophonic audio signals may be divided into their left audio channel signal and right audio channel signal components and transmitted to the proper ear cup. In another example, the systems and methods described herein may be used to determine when a pair of headphones are being worn on a user's head and/or are removed from a user's head. By determining when the headphones are being worn, the headphones may be able to automatically pause an audio signal and/or power off when a transition from on-head to off-head is detected.
