Benefits of technology

[0017]It is an object of the invention to provide for a wireless sound transmission system

Problems solved by technology

Wireless networking devices have a finite communication range which is limited by the output power of the transmitting device, the signal attenuation in the wireless channel and the sensitivity of the receiving device.
The limitations can be regulatory restrictions (maximum allowed output power), technical constraints (size of transmitting and receiving ante

Example

[0035]The present invention relates to a system for providing hearing assistance to at least one user, wherein audio signals are transmitted, by using a transmission unit comprising a digital transmitter, from an audio signal source via a wireless digital link to at least one receiver unit, from where the audio signals are supplied to means for stimulating the hearing of the user, typically a loudspeaker, but including any other type of stimulation, such as a cochlear implant electrode or an implantable electromechanical actuator coupled to an ossicle or directly to the cochlea.

[0036]The invention is not restricted to a particular kind of the wireless link. For example, the invention may be applied to an inductive link (magnetic near-field coupling between the antennas), as it may be used in hearing instrument body area networks (wherein hearing devices and accessories of hearing devices are worn on the user's body and / or are manually handled as hand-held devices by the user), or an...

Abstract

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).

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a system and a method for providing sound to at least one user, wherein audio signals from an audio signal source, such as a microphone for capturing a speaker's voice, are transmitted via a wireless link to a receiver unit, such as an audio receiver for a hearing aid, from where the audio signals are supplied to means for stimulating the hearing of the user, such as a hearing aid loudspeaker.[0003]2. Description of Related Art[0004]Wireless networking devices have a finite communication range which is limited by the output power of the transmitting device, the signal attenuation in the wireless channel and the sensitivity of the receiving device. The limitations can be regulatory restrictions (maximum allowed output power), technical constraints (size of transmitting and receiving antennas, electrical power consumed by transmitting device or receiving device), or the physical environment (e.g.,...
