“…Indeed, this result is further corroborated by the data published in [17,18]. There, the B/A of 1.3-butanediol was determined to be 10.9 ± 0.6 and was deduced from the phase modulation method using collinear mixing of 1 MHz and 10 MHz waves generated by planar acoustic sources.…”

The objective of this work is to develop an easy-to-build and robust setup for measuring the nonlinearity parameter B/A in fluids using ultrasound. The method is based on the pulse echo technique, using a single element broadband acoustic transducer, and requires electrical signal measurements. Results obtained in water and denatured alcohol validate the proposed procedure. The choice of a suitable primary wave frequency is discussed with regard to the transducer sensitivity. Further, the influence of the perturbations introduced by the experimental device nonlinearities, and the role of the reflector on the measured second harmonic field amplitude are investigated.

“…The sum and difference frequencies are generated by parametric interaction, which has been studied for a long time, 19 especially in tomographic applications, 20,21 and more recently to measure the nonlinear parameter ␤ in liquids. 22 Generally, radiation of sum-and difference-frequency sound from the nonlinear interaction region formed by the intersection of nonplanar modes in the waveguide is referred to as scattering of sound by sound. 18 The NPE code is initialized by a sine-wave packet, modulated by Gaussian envelopes having scale sizes 600 m in range and 150 m in depth, and centered at the frequency f ϭ30 Hz.…”

A hybrid method coupling nonlinear and linear propagation codes is used to study the nonlinear signature of long-range acoustic propagation for high-amplitude sources in an ocean waveguide. The differences between linear and nonlinear propagation are investigated in deep and shallow water environments. The spectral reshaping that occurs in nonlinear propagation induces two main effects: in shallow water, an unusual arrival time structure in the lowest order modes is observed, and in both shallow and deep water environments, there is a tendency to have acoustic energy more uniformly distributed across modes. Further, parametric low-frequency generation in deep water is a candidate for the coupling between water and sediments for T-wave formation.
