Abstract: An apparatus and method for communication using sound waves is disclosed. More particularly, orthogonal frequency division multiplexing scheme is used to transmit and receive digital data on sound waves. In one embodiment, the sound waves are used to exchange information. In another aspect, the sound waves are used to authenticate an individual or device.

Abstract: An apparatus and method for bidirectional communication using sound waves is disclosed. The invention uses a multi-carrier modulation scheme to transmit and receive digital data on acoustic waves. In one embodiment, acoustic waves having frequencies in the range between approximately 1 kHz to 3 kHz are used such that digital data can be transmitted by a standard speaker and microphone.
