Wireless sound transmission and method

A method for providing sound, the method comprising:

• providing an audio signal from an audio signal source to a transmission unit comprising a digital transmitter for applying a digital modulation scheme;
• encoding the audio signal,
• wherein encoding includes encoding such that each audio data block is distributed onto at least two audio data packets in such a manner that one of the audio data packets is a low-quality audio data packet including an encoded low-quality portion of the audio signal, and one of the audio data packets is a high quality audio data packet including a high-quality portion of the audio signal with regard to a low-quality portion, so that by decoding of the low-quality audio data packet only the low-quality portion of the audio signal is retrieved, whereas by decoding of both the low-quality and the high-quality audio data packets a high-quality portion of the audio signal is retrieved;
• transmitting the encoded audio signal via a digital wireless audio link from the transmission unit to a receiver unit,
• wherein the low-quality audio data packet is transmitted in a dedicated slot of a multiple access protocol frame and the high-quality audio packet is transmitted in another dedicated slot of the multiple access protocol frame, and
• wherein the receiver unit is configured to decode the low-quality audio data packet only while sleeping during the another slot dedicated to the transmission of the high-quality audio data packet;
• decoding the transmitted audio signal;
• and
• providing the decoded audio signal to a user.

A hearing device, the device comprising:

• a housing structure configured to be worn by a human,
• a receiver unit physically coupled to the housing structure, wherein the receiver unit is configured to receive an audio signal from a transmission unit,
• wherein the transmission unit is configured to encode the audio signal in such a manner that each audio data block is distributed onto at least two audio data packets in such a manner that one of the packets is a low-quality audio data packet including an encoded low-quality portion of the audio signal, and one of the packets is a high-quality audio data packet that includes a surplus of an encoded high-quality portion of the audio signal with regard to the low quality portion,
• wherein the transmission unit is configured to transmit the low-quality audio data packet in dedicated slots of a multiple access protocol frame and to transmit the high-quality audio data packet in other dedicated slots of the multiple access protocol frame, and
• wherein the receiver unit is configured to decode the low-quality audio data packet while sleeping during the slots dedicated to the transmission of the high-quality audio data packet.
