A method and system of establishing a wireless network for audio data transmission with a first and second audio devices having first and second transceivers, the first audio device being an audio signal transmission unit with a user operable switch, and the first and second audio devices being assistive listening devices. Periodically the second transceiver listens for pairing information, at at least one public frequency channel; operating the switch by the user to initiate pairing at any time during operation of the first audio device; the first transceiver transmitting pairing information at said at least one public frequency channel upon operation of the switch. The second audio device automatically pairs to the first audio device upon reception of pairing information from the first transceiver. The first and second transceivers are controlled so that reception of the pairing information from the first audio device is accepted by the second audio device.

Pairing method for establishing a wireless audio network

A hearing assistance system and method for wireless RF audio signal transmission from at least one audio signal source to ear level receivers, wherein a close-to-natural hearing impression is to be achieved. At least one parameter of the RF signal as received from a transmission unit at a respective receiver unit to create left ear RF signal measurement data and right ear RF signal measurement data, respectively. The angular localization of each transmission unit is obtained by comparing, for each transmission unit, the left ear RF signal measurement data and the right ear RF signal measurement data. The audio signals are processed and distributed according to the estimated angular localization of each transmission unit in a manner so that the angular localization impression of the audio signals from each transmission unit as perceived by the user corresponds to the estimated angular localization of the respective transmission unit.

Hearing assistance system and method

Microphone for hearing aids

A system for providing hearing assistance to at least one user, having: at least one audio signal source () for providing audio signals; a transmission unit () for wireless transmission of audio signals; at least one receiver unit () for wireless reception of audio signals from the transmission unit; a device () for stimulating the hearing of the user according to audio signals supplied from the at least one receiver unit. The transmission unit has both an analog transmitter () for applying an analog modulation scheme and a digital transmitter () for applying a digital modulation scheme in order to transmit the audio signals from the audio signal source () simultaneously via an analog audio link () and a digital audio link ().

An implanted hearing aid or hearing device includes at least one permanent magnet () positioned in the area of the middle ear, as well as at least one coil (), with at least one permanent magnet () attached to the promontory ().

Implanted hearing aids

An implantable electromagnetic transducer for hearing aids and process for tuning its frequency response are disclosed. The transducer is provided with a static transducer part which includes a hermetically sealed transducer housing and a ring coil arrangement which is mounted inside, and with a dynamic part which is mechanically connected to the static transducer part via at least one connecting element which is coupled in the implanted state to part of the body of the implant wearer via at least one connecting element. The implantable transducer has a permanent magnet arrangement, which interacts with the ring coil arrangement and which is supported to be able to vibrate by means of a support in the direction of the axis of the ring coil arrangement, with at least one connecting element being made as a multifunction element which is part of the support and/or part of the hermetically tight transducer housing. The mechanical properties of the multifunction element are selected for achieving a set frequency response of the transducer.

Implantable transducer for hearing aids and process for tuning the frequency response of one such transducer

A percutaneous or transcutaneous connecting device, featuring at least one passage or a passage-free connection through the outer surface and in particular the skin of a living being, incorporates a permanent magnet ( ) which is positioned in the area of the outer surface such as the skin ( ) with its poles essentially extending parallel thereto. In the case of a percutaneous connecting device, physical passages ( ) are provided which extend through the outer surface of the living being, whereas in the case of a transcutaneous connecting device the transfer of electrical or electromagnetic signals and/or electrical energy takes place without physical passages, instead employing for instance coils.

Percutaneous or transcutaneous access into the body

A hearing aid implant to be mounted in the ear includes a housing and an actuator mounted on the housing. The actuator is movable relative to the housing. An electromechanical drive transducer works between the housing and the actuator. The housing is attached to the outer ear part of the ear drum area and the actuator has an end facing away from the housing that works in the middle ear.
