  • Patent number: 11234084
    Abstract: The phase responses of a first and a second microphone are adjusted with first and second filters that filter their microphone signals. The first filter corresponds to a first contribution to a phase shift between the microphones and includes a first adaptation parameter. The second filter corresponds to a second contribution to the phase shift and has a second adaptation parameter. A global filter, which is formed with the first and second filters, represents the first and second contributions to the phase shift and includes the first and second adaptation parameters. The global filter determines a first value for the first adaptation parameter and a second value for the second adaptation parameter via a multidimensional optimization. The phase responses are adjusted by applying the first filter and the second filter to at least one of the microphone signals with the adaptation parameters set to the first and second values, respectively.

  • Patent number: 11190887
    Abstract: The disclosed technology generally relates to a hearing device positioned partially or completely within an ear canal. In some implementations, the hearing device is an ITE with an oval-shaped or elongated battery, where the battery is positioned at an angle relative to a faceplate of the ITE. The hearing device can be a rechargeable, where the rechargeable battery is positioned (e.g., titled) between at an angle between 10 to 25 degrees relative to the faceplate of the ITE. In some implementations, the faceplate of the ITE is configured to enable the battery to pivot or adjust its angle such that the battery position can be adjusted to use space more efficiently. In some implementations, the battery 220 has a long axis, where the long axis is longer than any other battery axis, and the long axis extends from the faceplate at a non-perpendicular angle (e.g., 10 to 35 degrees).
