Acoustic transmitter....-A transmitter of acoustic energy which propagates that energy in a directional manner is described. An acoustic signal generator is connected at one end of an acoustic transmission line which exhibits a certain characteristic impedance. The line has a number of ports spaced along its length.... acoustic energy is partitioned evenly at each port so as to define an array of equal strength radiators having directional acoustic signal propagating characteristics. 2, record 1, English, - acoustic%20transmitter
