An in-ear device is implemented as part of an audio system to present a user with improved audio content within an artificial reality system. The in-ear device is a fully integrated device with an internal microphone, an external microphone, and a transducer in which portions of the transducer form portions of the body of the device. This integration of transducer into the body of the in-ear device reduces the size of the in-ear device and allows for placement deeper within the ear canal of the user. The transducer generates audio content based on instructions received from an audio system that may be located on a device that is external to the in-ear device. The external microphone provides hear-through functionality, while the internal microphone provides feedback information to the audio system.

An ear cup housing has several reference microphones, an error microphone and a speaker. A processor drives the speaker for acoustic noise cancellation and transparency, by processing the microphone signals, and performs an oversight process by adjusting the reference microphone signals in response to detecting wind noise events and scratch events. In another aspect, the ear cup housing has an outside face that is joined to an inside face by a perimeter and the reference microphones are on the perimeter. Other aspects are also described and claimed.

Disclosed is a signal processing apparatus including a surrounding sound signal acquisition unit, a NC (Noise Canceling) signal generation part, a cooped-up feeling elimination signal generation part, and an addition part. The surrounding sound signal acquisition unit collects a surrounding sound to generate a surrounding sound signal. The NC signal generation part generates a noise canceling signal from the surrounding sound signal. The cooped-up feeling elimination signal generation part generates a cooped-up feeling elimination signal from the surrounding sound signal. The addition part adds together the generated noise canceling signal and the cooped-up feeling elimination signal at a prescribed ratio.

The technology disclosed herein enables ambient noise level determination at an endpoint using a secondary audio capture system for the endpoint. In a particular embodiment, a method includes during a communication session, receiving an audio signal representing sound captured by a secondary audio capture system for an endpoint on the communication session. A primary audio capture system for the endpoint captures voice communications from a user of the endpoint for the communication session. The method further determining an ambient noise level for the endpoint from the audio signal and, in response to determining that the ambient noise level satisfies a loudness criterion, presenting a notification to the user about the ambient noise level.

A method for operating a hearing aid includes providing the hearing aid with an ANC unit and a speech recognition unit. The ANC unit is configured to process multiple frequency ranges and at the same time to suppress noises from the surroundings in each of these frequency ranges using a respectively settable ANC strength. The speech recognition unit recognizes for each of the frequency ranges whether or not speech is present therein. The ANC unit is controlled in such a way that the ANC strength is set for a respective frequency range depending on whether or not the speech recognition unit has recognized speech in that frequency range. A hearing aid having a control unit configured to execute the method is also provided.

A sound processing apparatus includes a receiving module configured to receive audio signals of one or more sounds acquired by a personal sound device, a processing module configured to use a sound processing model to perform: classification processing in which a type of a scenario where a user of the personal sound device is located is determined based on the audio signals; identification processing in which each of the one or more sounds is determined as a desired sound or an undesired sound based on the determined type of the scenario, and filtering processing in which filtering configuration is performed based on a result of the identification processing. The audio signals are filtered based on the filtering configuration, and an output module is configured to output the filtered audio signals, so as to provide same to the user.

A voice signal processing method includes acquiring a near-end noise signal and a near-end voice signal by using at least one microphone, acquiring a far-end voice signal according to an incoming call, determining a noise control parameter and a voice signal change parameter based on at least one of information about the near-end voice signal, information about the near-end noise signal, or information about the far-end voice signal, generating an anti-phase signal of the near-end noise signal based on the noise control parameter, changing the far-end voice signal to improve articulation of the far-end voice signal based on information related to at least one of the voice signal change parameter, the near-end noise signal, or the anti-phase signal, and outputting the anti-phase signal and the changed far-end voice signal.

An electronic device includes one or more pose sensors for detecting a pose of a user of the electronic device relative to a first physical environment and is in communication with one or more audio output devices. While a first pose of the user meets first presentation criteria, the electronic device provides audio content at a first simulated spatial location relative to the user. The electronic device detects a change in the pose of the user from the first pose to a second pose. In response to detecting the change in the pose of the user, and in accordance with a determination that the second pose of the user does not meet the first presentation criteria, the electronic device provides audio content at a second simulated spatial location relative to the user that is different from the first simulated spatial location.
