| Zusammenfassung: | A method and apparatus for effectively communicating data along an acoustic transmission path (15). The method comprises driving an acoustic transmitter (40) to send a data signal along the acoustic transmission path (15), where the signal is distorted by ambient noise. The distorted signal is input to a spaced apart plurality of sensors (42a, 42b, 42c, 42d) so that consequent time-delayed signals provide reinforcement of the basic signal and attenuation of the ambient noise component when combined. |
