Enhanced concert audio system

An audio enhancement system comprising:

• at least one main electro-acoustic transducer for generating a primary sound in response to a first electrical signal;
• transmission means for converting said first electrical signal into a transmission signal and for wirelessly transmitting said transmission signal;
• and
• at least one personal electro-acoustic transducer unit, said at least one personal electro-acoustic transducer unit including
• at least one auxiliary electroacoustic transducer having a low maximum output sound level, wherein said maximum output sound level can be heard by people only within a range of several feet of said electro-acoustic transducer in ambient sound,
• a receiver for receiving and converting said transmission signal into a second electrical signal, said at least one auxiliary electro-acoustic transducer generating an augmenting sound in response to said second electrical signal, and
• delay means for delaying said second electrical signal by a period of time, said delay means further comprising an automatic adjustment means for automatically adjusting said period of time to be substantially equal to an amount of time required for said primary sound to reach said personal unit, such that said augmenting sound augments said primary sound to enhance audio perception by at least one user within said range of said auxiliary electro-acoustic transducer.

A method of enhancing audio sound, said method comprising the steps of:

• generating a primary sound in response to a first electrical signal;
• converting said first electrical signal into a transmission signal;
• wirelessly transmitting said transmission signal;
• providing at least one personal electro-acoustic transducer unit, said at least one personal electro-acoustic transducer unit including at least one auxiliary electro-acoustic transducer having a low maximum output sound level, wherein said maximum output sound level can be heard by people only within a range of several feet of said electro-acoustic transducer in ambient sound, and a receiver;
• receiving and converting in said personal unit said transmission signal into a second electrical signal;
• generating in said at least one auxiliary electro-acoustic transducer an augmenting sound in response to said second electrical signal;
• and
• delaying at least one of said first and said second electrical signals by a period of time substantially equal to an amount of time required for said primary sound to reach said at least one personal unit, such that said augmenting sound augments said primary sound to enhance audio perception by at least one user within said range of said at least one auxiliary electro-acoustic transducer, wherein said transmitting step includes transmitting said transmission signal via a single predetermined channel, said method including the further step of delaying said second electrical signal in said at least one personal electro-acoustic transducer unit by a period of time substantially equal to an amount of time required for said primary sound to reach said at least one personal electro-acoustic transducer unit.
