ABSTRACT:
An audio enhancement system and method is provided wherein a wireless headphone system comprises a transmitter and a receiver including a synchronization device which utilizes electromagnetic locating signals to locate the position of the receiver with respect to the transmitter. The transmitter for this system will broadcast a frequency modulated (FM) signal on a number of separate channels in the 900 MHz band range. Each channel will carry the same audio information, however, each successive channel will have its audio signal delayed by a preset time period, e.g. 50 ms, relative to the previous channel. The headset receiver, supporting position location signals, and associated hardware will select the appropriate channel depending on the listener's distance from the main loudspeakers. These channels are laid out such that when in a large venue, and if the proper channel is chosen, the sound received electronically over the wireless channel will be approximately in phase with the sound arriving to the listener from the main loudspeakers.
