Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

A wireless power system includes a wireless power transmitting device such as a wireless charging mat for charging devices such as a cellular telephone and an earbuds battery case. The earbuds battery case receives earbuds and charges the earbuds from a battery. The wireless charging mat supports bidirectional in-band communications between the cellular telephone and the earbuds battery case. The earbuds battery case provides the cellular telephone with information on the battery charge level associated with the battery in the earbuds battery case and a battery charge level associated with each earbud in the earbuds battery case. The cellular telephone receives battery charge level information through the wireless charging mat and displays corresponding indicators. The earbuds battery case has a visual output device such as a light-emitting diode that is illuminated to indicate that the earbuds battery case is being charged.

Devices, systems and processes for providing an adaptive audio environment are disclosed. For an embodiment, a system may include a wearable device and a hub. The hub may include an interface module configured to communicatively couple the wearable device and the hub and a processor, configured to execute non-transient computer executable instructions for a machine learning engine configured to apply a first machine learning process to at least one data packet received from the wearable device and output an action-reaction data set and for a sounds engine configured to apply a sound adapting process to the action-reaction data set and provide audio output data to the wearable device via the interface module.

The disclosure relates to a hearing system comprising a first hearing device and a second hearing device configured to be worn at a respective ear of a user, each hearing device comprising a displacement sensor configured to provide respective displacement data indicative of a rotational displacement and/or a translational displacement of the hearing device, and a processing unit communicatively coupled to the displacement sensors. The disclosure further relates to a corresponding method of operating a hearing system, and a computer-readable medium storing instructions to perform the method.

A method performed by a programmed processor of an in-ear headphone that is to be worn by a user. The method obtains, over a wireless communication link and via a first wireless connection that uses an accessory profile, a first request, from an audio source device, to start a measurement process. In response to obtaining the request, the method 1) establishes, over the link, a second wireless connection that uses an audio distribution profile between the headphone and the source device, 2) obtains, via the second wireless connection, an audio signal for driving a speaker of the headphone to output sound, 3) responsive to the outputted sound, determining a fit parameter, and 4) transmitting the fit parameter to the source device via the first wireless connection.

Disclosed herein is a mixed reality application to use a multi-channel audio input to identify a character and origin of a given sound, then present a visual representation of the given sound on a near eye display. The visual representation including a vector to the source of the sound. The visual representation further including graphical elements that describe various attributes of the given sound including the magnitude, directionality, source, and threat level. Where the source of the given sound is moving, the visual representation shifts to illustrate the movement.

An audio data transmission method, an audio data transmission system, and an audio data transmission device are described. The audio data transmission method comprises: receiving first channel audio data from an audio source device based on a wireless communication protocol by a first audio data receiving device, receiving second audio channel audio data from the audio source device based on the wireless communication protocol by a second audio data receiving device, starting to receive the first channel audio data and the second channel audio data by one of the first and second audio data receiving devices when a communication quality between the audio source device and another one of the first and second audio data receiving devices fails to meet a preset requirement; and forwarding the first or second channel audio data from the one of the first and second audio data receiving devices to the another one of the first and second audio data receiving device. Thus, the present invention utilizes characteristics of independent fading at different spatial positions, improves reliability of wireless communication and enhances communication quality through a spatial diversity gain.

Transducer steering and configuration systems and methods using a local positioning system are provided. The position and/or orientation of transducers, devices, and/or objects within a physical environment may be utilized to enable steering of lobes and nulls of the transducers, to create self-assembling arrays of the transducers, and to enable monitoring and configuration of the transducers, devices, and objects through an augmented reality interface. The transducers and devices may be more optimally configured which can result in better capture of sound, better reproduction of sound, improved system performance, and increased user satisfaction.

A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.

In an audio apparatus including a first device and a second device that each receive the same audio data transmitted from a source device, a device having the worse reception environment of the audio data out of the first device and the second device, operates as a primary device that performs a retransmission request for the audio data to the source device, and a device having the better reception environment operates as a secondary device that performs the retransmission request for the audio data to the primary device.
