A headset with automatic noise reduction mode switching is provided to enable better call experience when conducting a call. The headset comprises at least one or more earphones, one or more microphones, a processor, and an active noise cancellation circuit, connected at least with the processor. The processor is configured to determine whether a call is being conducted using the headset, and if a call is being conducted, to switch the active noise cancellation circuit from a first ANC mode to a second ANC mode.

Disclosed is a wireless audio device, which includes at least one microphone, at least one speaker, at least one sensor, a processor, and a memory storing instructions, and the instructions that, when executed by the processor, cause the wireless audio device, while the wireless audio device outputs a sound for reducing an outside sound acquired through the at least one microphone through the at least one speaker, to identify a specified outside sound of the outside sound acquired through the at least one microphone, to output a notification sound for indicating that the specified outside sound is identified through the at least one speaker, to identify a motion of a user of the wireless audio device through the at least one sensor, in response to outputting the notification sound, and to stop the output of the sound for reducing the outside sound based on the identified motion.

A hearing device adapted for being located at or in an ear of a user, or for being fully or partially implanted in the head of a user comprises a) an input unit for providing at least one electric input signal representing sound in an environment of the user, said electric input signal comprising a target speech signal from a target sound source and additional signal components, termed noise signal components, from one or more other sound sources, b) a noise reduction system for providing an estimate of said target speech signal, wherein said noise signal components are at least partially attenuated, and c) an own voice detector for repeatedly estimating whether or not, or with what probability, said at least one electric input signal, or a signal derived therefrom, comprises speech originating from the voice of the user. The noise signal components are identified during time segments wherein the own voice detector indicates that the at least one electric input signal, or a signal derived therefrom, originates from the voice of the user, or originates from the voice of the user with a probability above an own voice presence probability (OVPP) threshold value. A method of operating a hearing device is further disclosed.

A method for use in a biometric process, comprising: for a first function and a second function, applying an acoustic stimulus to a user's ear; and for the second function: receiving a response signal of a user's ear to the acoustic stimulus; and extracting, from the response signal, one or more features for use in a biometric process, wherein the first function is a function other than to induce the response signal for use in the biometric process.

An information processing system includes a processor configured to detect biological information measured at a head and control a volume of an ambient sound output from a speaker provided in a device which is worn so as to cover an ear according to the detected biological information.

Various implementations include systems for processing microphone audio signals for a wearable audio device. In particular implementations, a method for processing signals includes: capturing an internal signal with an inner microphone configured to be acoustically coupled to an environment inside an ear canal of a user; extracting a low frequency audio signal from the internal signal; capturing an external signal with an external microphone configured to be acoustically coupled to an environment outside the ear canal of the user; extracting a high frequency audio signal from the external signal; and mixing the high frequency audio signal with the low frequency audio signal.

Playback devices such as headphone devices can include an earpiece configured to be positioned adjacent a user's ear. The earpiece can include a transducer having a diaphragm configured to face toward the user's ear when the earpiece is positioned adjacent the user's ear, as well as an outlet vent in fluid communication with the transducer and a microphone. A support member within the earpiece includes a first opening aligned with the microphone and a second opening aligned with the outlet vent. An acoustic mesh extends over the first opening and the second opening, wherein the mesh has a substantially uniform acoustic impedance.

An audio apparatus, e.g. for rendering audio for a virtual/augmented reality application, comprises a receiver (201) for receiving audio data for an audio scene including a first audio component representing a real-world audio source present in an audio environment of a user. A determinator (203) determines a first property of a real-world audio component from the real-world audio source and a target processor (205) determines a target property for a combined audio component being a combination of the real-world audio component received by the user and rendered audio of the first audio component received by the user. An adjuster determines a render property by modifying a property of the first audio component indicated by the audio data for the first audio component in response to the target property and the first property. A renderer (209) renders the first audio component in response to the render property.

A speaker of a hearing instrument generates a sound that includes a range of frequencies. Furthermore, a microphone of the hearing instrument measures an acoustic response to the sound. A processing system classifies, based on the acoustic response to the sound, a depth of insertion of an in-ear assembly of the hearing instrument into an ear canal of a user. Additionally, the processing system generates an indication based on the depth of insertion of the in-ear assembly of the hearing instrument into the ear canal of the user.

An active noise cancelling system (20) comprising: an earphone (8′) comprising: an electro-acoustic driver (11); and at least one sensing microphone (12, 13); tunable active noise cancelling circuitry (7) operative to receive a signal from the at least one sensing microphone (12, 13), the tunable active noise cancelling circuitry (7) being pre-configured in a standard tuning for a reference ear and comprising at least one noise-control filter (14, 15); and a tuning module (24) operative to configure the earphone (8′) for an individual wearer by: comparing acoustic coupling of the earphone (8′) to the individual wearer's ear with acoustic coupling to the reference ear to determine a deviation in acoustic coupling; and using the determined deviation in acoustic coupling to modify the tunable active noise cancelling circuitry (7) by a predetermined degree based on the determined deviation in acoustic coupling.
