1. A system for providing sound to at least one user, comprising:

  • at least one audio signal source for providing audio signals;

    a transmission unit comprising a digital transmitter for applying a digital modulation scheme in order to transmit the audio signals as data packets from the audio signal source via a wireless digital audio link;

    at least one receiver unit for reception of audio signals from the transmission unit via the digital audio link, comprising at least one digital receiver;

    means for stimulating the hearing of at least one user according to audio signals supplied from the receiver unit;

    wherein the transmission unit is adapted to transmit each data packet in a separate slot of a TDMA frame at a different frequency according to a frequency hopping sequence,wherein, in at least some of the slots, the audio signals are to be transmitted as audio data packets, wherein a same audio packet is to be transmitted at least twice in a same TDMA frame, without expecting acknowledgement messages from the at least one receiver unit, andwherein the TDMA frames are structured for unidirectional broadcast transmission of the audio data packets, without individually addressing the at least one receiver unit.
