A method and system for daisy chaining tournament audio controllers, where the method comprises, in a headset coupled to a first audio controller, the first audio controller being in a daisy chain of audio controllers: receiving a chat signal from a second audio controller in the daisy chain of audio controllers, receiving a microphone signal from a microphone in the headset, summing the chat signal with the microphone signal, communicating the summed signal to a third audio controllers in the daisy chain, and communicating the chat signal to the headset. The microphone signal may be removed from the summed chat signal and microphone signal by adding a second microphone signal 180 degrees out of phase with the microphone signal. The chat signal may be summed with the microphone signal at an amplitude set by a user of the headset after the removal of the microphone signal.

Disclosed herein are apparatuses for manipulation of an ear device within the ear canal of a subject. Also disclosed herein are methods of using said apparatuses for the insertion, removal, or other manipulations of the ear device. Also disclosed herein are methods of making the apparatuses, and kits containing the apparatus with instructions for use.

The present disclosure relates in a first aspect to a head-wearable hearing instrument comprising first and second portions and a radio-frequency data communication interface configured to transmit and receive data packets at transmit and receipt time slots, respectively, through a wireless communication channel. The head-wearable hearing instrument comprises a connector assembly configured to electrically and mechanically interconnect the first portion with the second portion. The second portion comprises a sensor configured to measure a physical property and generate sensor data representative of the measured physical property. The head-wearable hearing instrument further comprises a wired data communication link extending between the first and second portions through the connector assembly for transmission of sensor data during transmit time slots. Said transmit time slots of the sensor data and at least said receipt time slots of the wireless communication channel are non-overlapping in time.

To promote further improvement in usability. A signal processing apparatus (10) includes an acquisition unit (111) that acquires an acoustic characteristic in a user's ear, isolated from the outside world, an NC filter unit (1122) that generates sound data having a phase opposite to an ambient sound leaking into the user's ear, a correction unit (1123) that corrects the sound data by using a correction filter, an a determination unit (1121) that determines a filter coefficient of the correction filter based on the acoustic characteristic.

A signal representing a sound can be received. A machine learning model can be run to identify that the sound triggers a reaction in a user hearing the sound. A preventive action can be automatically activated to mitigate the reaction. The user's reactions can be monitored. Responsive to determining that the user's reaction has been mitigated or suppressed, the preventive action can be deactivated. The machine learning model can be retrained using at least the signal as new training data.

Embodiments of the disclosure relate to methods, apparatus and systems for authentication of a user. The described embodiments relate to obtaining ear biometric data for a user to be authenticated. The ear biometric data comprises one or more features characteristic of the user's ear canal and an associated fit metric indicative of a positioning of a personal audio device relative to the user's ear canal, the personal audio device comprising a transducer for application of acoustic stimulus to the user's ear to obtain the ear biometric data. The user may be identified as a particular authorised user based on one or more features and the associated fit metric.

A method performed by a first electronic device, the method includes, while engaged in a call with a second electronic device, initiating a joint media playback session in which the first and second electronic devices independently stream media content for synchronous playback; driving a speaker with a mix of a downlink signal of the call and an audio signal of the media content at an overall volume level; receiving a user-adjustment at a single volume control for the first electronic device to reduce the overall volume level; in response to the user adjustment, applying a first gain adjustment to the downlink signal and a second gain adjustment to the audio signal; and driving the speaker with a mix of the downlink signal and the audio signal at the reduced volume level.

A headphone is configured to be used in combination with an in-ear earphone, and includes: an earmuff configured to be fitted over an auricle; an earmuff pickup arranged on an outer side of the earmuff and configured to collect an environmental sound; and a first speaker arranged on an inner side of the earmuff and configured to perform at least one of following actions: playing a noise-cancellation sound corresponding to the environmental sound collected by the earmuff pickup, or playing an audio. When the headphone is in use, the inner side of the earmuff and the auricle define an accommodating space for accommodating a part of the in-ear earphone exposed out of an external auditory canal. The headphone and the auricle define an accommodating space for accommodating the in-ear headphone.

A face mask can both actively cancel sounds and passively attenuate sounds spoken by the user to prevent the sounds from reaching non-intended recipients positioned near the user. The mask can not only reduce the user's voice from escaping the mask but can also be used to reduce external sounds from reaching inside the mask. Thus, a user can wear the mask in public and talk on their phone without disturbing others around them. The mask can include at least one microphone and at least one audio speaker disposed inside and/or outside the mask. Sounds received by the microphone can be processed by a microphone and computing electronics to provide an output to the audio speaker that can appropriately attenuate the sound received by the microphone, via acoustic cancelation. The mask can not only be used to cancel sounds but may also be used to amplify sounds when desired.

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.
