A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.

A trauma scene monitoring system includes a medic-worn illumination device, a casualty-worn informatics system, and a remote monitoring station. The illumination device includes a frame with boom-mounted light sources positioned below the wearer's eyes near the zygomatic bones, thus orienting the light sources to project light in the direction of the wearer's view. Also included are audio/video means to capture audio/video information from a scene attended by the medic, and a telemetry unit to transmit that information to the remote monitoring station. The casualty-worn informatics system is integrated within a headband worn by a monitored individual. The informatics system includes sensors to provide the monitored individual's vital statistics and a telemetry unit to transmit data concerning the monitored individual to the remote monitoring station. At the remote monitoring station, receiving and presentation stations provide views of the data concerning the monitored individual and audio/video data from the medic-worn illumination device.

A wireless earphone comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.

The disclosure is directed to methods for transmitting vibrations via an electronic and/or transducer assembly through a user or wearer's tooth, teeth, jaw, and/or other bones. The disclosure is further directed to a system for transmitting vibrations via an electronic and/or transducer assembly through a user or wearer's tooth, teeth, jaw and/or other bones. The disclosure is further directed to an oral apparatus for implementation of methods and systems described herein.

A wireless earring assembly for discretely streaming audio into a user's ears includes a pair of earrings that each includes an ornament, a stud extending away from the ornament and a retainer that is slidable onto the stud. A pair of audio units is each integrated into the ornament of a respective one of the earrings. Each of the audio units is in wireless communication with an audio source such that each of the audio units receives an audio signal from the audio source. Additionally, each of the audio units has sound emitting capabilities to emit audible sounds from the audio signal toward the user's ear.

A voice sound reduction device having a sound dampening cup that conforms to a user's face around the user's mouth, a microphone on an interior of the sound dampening cup electronically paired to a communication device, and a means for positioning the sound dampening cup to a user's face.

The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

A biofeedback headset for providing input to and receiving output from an information handling system may include a controller to send and receive audio signals to and from the information handling system and send biofeedback signals to the information handling system; one or more speakers mounted to a wearable head band to provide audio output from the information handling system to a user; and a mouthpiece operatively coupled to the wearable headband including: a microphone to receive audio input from the user; a pressure sensor to detect a breathing rate and amplitude of the user and, with the controller, provide breathing rate and amplitude biofeedback signals to the information handling system; and a gas sensor to detect a composition of air at the mouthpiece as the user respirates and, with the controller, provide air composition biofeedback signals to the information handling system.

A method for providing sound to at least one user, in which audio signals are captured and transformed into audio data that is transmitted to at least one receiver unit; audio signals are generated from the received audio data and the hearing of the user(s) stimulated thereby; wherein the audio data is transmitted as audio data packets in separate slots of a TDMA frame structure, wherein the transmission unit and the receiver unit(s) are synchronized to form a wireless network, wherein each TDMA frame structure has at least one listening slot during which the synchronized network members do not transmit data and at least one network members listens, and wherein control data is transmitted from an external control device according to a sequence pattern selected according to the duration and periodicity of the listening slot(s) to be received by the at least one synchronized network member during said listening slot(s).

Various techniques are provided to implement and use an earpiece having an attachment mount. In one example, an earpiece includes an arcuate rib having a lobe disposed on an upper end thereof and configured to engage with a crus of a helix and an antihelix of a user's ear. The earpiece also includes a mount extending from the arcuate rib and comprising a snap clip configured to engage and position an audio device in contact with the user's ear. Other implementations and related methods are also provided.
