AB Nonlinear acoustics offers a new range of acoustic applications that are currently beingexploited. The parametric nonlinear effect—the occurrence of low frequencies with modulatedhigh-frequency emission—is of particular interest. This work provides a systematic exposition of thetheoretical framework on which the so-called parametric nonlinear effect is based. In relation to thisbehavior is an analytical discussion of how to solve the problem for two cases: (i) nonlinear behaviorwith modulation, and (ii) parametric emission of two monochromatic waves (bi-frequency). Subsequently,parametric emission experiments were carried out in air and water using the same transducerto compare the results with those obtained theoretically. In this sense, directivity and attenuation measurementsare obtained. Conclusively, this research offers a proof of concept for underwater acousticcommunications. It is characterized by the transmission of a binary sequence through FrequencyShift Keying (FSK) modulation, and the subsequent decoding of each received bit (either 1 or 0)utilizing advanced signal processing with the cross-correlation technique. This paper accentuates thesignificant potential of employing the parametric effect for specialized communication applications.
