Abstract
A system providing sound to a user, having at least one audio signal source; a transmission unit with a digital transmitter which transmits audio signals via a wireless digital audio link as audio data packets, each packet having a start frame delimiter, audio data and a frame check sequence; at least one receiver unit having at least two digital receivers connected to a common processing unit and an antenna, and including a demodulator and a buffer, and a mechanism for stimulating the hearing of the user. Each receiver receives, verifies and buffers the audio data packets, and the processing unit reads an audio data packet from the buffer of one of the receivers. If the packet is correctly received by the receiver, the buffer of the other receivers is flushed, and if the packet has been incorrectly received, the audio data packet from the buffer of another receiver is read.
