The remote-controller includes an integrated microphone and receive an audio message. Audio from the microphone is effectively instantly delivered to at least one speaker of the headphones via a wireless channel.

Systems, devices, and methods for initiating an action based on location of a first device are provided. The first device, such as an earbud, includes a Bluetooth receiver. The Bluetooth receiver is configured to receive a wave signal transmitted by a second device, such as a smartphone. The first device further includes a processor. The processor is configured to calculate a location of the first device relative to the second device based on the wave signal. The processor is further configured to determine a zone status of the first device based on the location of the first device relative to the second device and a predetermined zone. The processor is further configured to initiate the action based on the zone status.

A public address method for live broadcast, in a helmet, of an audio signal conditioned from a plurality of raw audio channels, includes a pre-processing phase including the operations that consist of taking into account characteristics of the auditory perception of the listener; correcting each channel as a function of the characteristics of the auditory perception of the listener; a mixing phase including the production, from the channels thus pre-processed, of a mixed audio signal; a post-processing phase including the operations that consist of: measuring the sound level of a background noise; correcting the mixed audio signal as a function of the sound level of the background noise; a phase of reproducing, in the helmet, the conditioned audio signal resulting from post-processing.

Provided a robot for assisting hearing of a user, while minimizing an influence on the surroundings. The robot includes a speaker, a microphone configured to recognize a voice, a processor configured to acquire a position of a user's face when a hearing aid command is acquired on the basis of the voice recognized through the microphone, and a driving unit configured to cause the speaker to be moved toward the position of the user's face, wherein the processor acquires a sound which is a target of hearing aid, generates an assistant sound by amplifying a predetermined frequency band of the sound or converting the predetermined frequency band of the sound into a different frequency band, and outputs the assistant sound through the speaker.

A wireless communication method and a system comprising a first audio source unit and at least a second audio source unit each comprising; a connection management interface for connecting to a network topology, a protocol management interface, a management link and a communication link, and during a configuration period the first audio source unit may be configured to listen for a notification packet via the management link, and, based on a first criteria, the first audio source unit may be configured to establish, via the protocol management interface, a communication group and a respective communication frame. Furthermore, where the first audio source unit may be a coordinator of the communication group, the coordinator may then be configured to establish notification packets in the communication frame, and the notification packets may then be transmitted via the management link assigned to a first time interval in the communication frame. During the configuration period, the second audio source unit may be configured to listen for a notification packet received? via the management link of the second audio source unit, the second audio source unit receives at least the notification packet and may be configured to extract, via a protocol management interface link, information of the management link of the coordinator from the received notification packet, and the second audio source unit may then be configured to transmit an ID information via the management link of the coordinator of the communication group, and where the coordinator may be configured to assign a second time interval for a communication link of the second audio source unit in the communication frame, the second audio source unit may then be configured to become an audio source member of that communication group. During a data communication period the second audio source member may be configured to communicate via the communication link of the audio source member at the second time interval in the communication frame to a sink unit.
