Abstract: In general, in one aspect, a hearing aid has an ANR circuit and an ear tip that acoustically occludes the ear. Such a hearing aid provides greater gain to sounds than would be stable in the same hearing aid with a vented ear tip. The ear tip and the ANR circuit in combination attenuate sounds reaching the ear canal through the hearing aid to a first level. The hearing aid detects sounds arriving at a microphone, amplifies those sounds, and provides the amplified sounds to the ear canal at a second level and later in time than the same sounds arrive at the ear canal through the ear tip. The first level is at least 14 dB greater than the second level, such that the amplified sounds do not interact with the passive sounds to result in spectral combing.

Abstract: A noise cancelling headset includes first and second earpieces, each earpiece including a respective feedback microphone, a respective feed-forward microphone, and a respective output driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal. An output interface provides the first output signal as an output from the headset.

Abstract: A noise cancelling headset includes an earpiece, the earpiece including a feedback microphone, a feed-forward microphone, and a noutput driver. A first feedback filter receives an input from at least the first feedback microphone and produces a first filtered feedback signal. A first feed-forward filter receives an input from at least the first feed-forward microphone and produces a first filtered feed-forward signal. A first summer combines the first filtered feedback signal and the first filtered feed-forward signal and produces a first output signal.

Abstract: A case for a portable electronic device includes an enclosed, elongated space extending within the case from an opening in an interior surface of the case. The opening corresponds to the location of a microphone in the device. The enclosed space is tapered to an increasingly smaller cross-section as it extends away from the opening. A first edge of the enclosed space aligns along most of its length with an exterior surface of the case. A screen covers a second opening in the exterior surface of the case along the first edge of the elongated space and provides an acoustic resistance between the elongated space and air outside the case through the second opening. A gasket located at the first opening couples the elongated space to the microphone of the electronic device.

Abstract: A conversation assistance system with a bi-lateral array of microphones arranged externally of a space that does not include any array microphones, where the space has a left side, a right side, a front and a back, the array comprising a left side sub-array of multiple microphones and a right side sub-array of multiple microphones, where each microphone has a microphone output signal, and a processor that creates from the microphone output signals a left-ear audio signal and a right-ear audio signal. The left-ear audio signal is created based on the microphone output signals from one or more of the microphones of the left-side sub-array and one or more of the microphones of the right-side sub-array and the right-ear audio signal is created based on the microphone output signals from one or more of the microphones of the left-side sub-array and one or more of the microphones of the right-side sub-array.

Abstract: A headset includes an acoustic structure, a first microphone located outside the acoustic structure, a second microphone located inside the acoustic structure, and an output driver configured to receive an antinoise signal based on a combination of input from the first and second microphones. A voice signal of a user of the headset is generated using input from the first and second microphones. The first microphone could be a feed-forward microphone that provides input to a feed-forward filter to produce a filtered feed-forward signal for producing the antinoise signal. The second microphone could be a feedback microphone that provides input to a feedback filter to produce a filtered feedback signal for producing the antinoise signal.

Abstract: Various implementations include systems for processing audio signals. In particular implementations, a process includes receiving an audio signal, wherein the audio signal includes a speech component of the user and a noise component; filtering the audio signal with a self-speech filter that utilizes an intrinsic user vector to filter out the speech component, wherein the intrinsic user vector is determined based on a voice input of the user; and outputting a filtered audio signal in which the speech component of the user has been substantially removed from the audio signal.
