In this work we present a prototype of a compact linear array with three elements that using the parametric acoustic effect is able to reproduce the acoustic signature of Ultra High Energy neutrino interaction in water. To mimic this signal is non-trivial since it is a very directive bipolar transient signal with cylindrical symmetry. We characterise the prototype by measuring the signal waveform, the attenuation, intensity variation and directivity. We also study different kind of signals to conclude the best application for the array. Finally, we propose other underwater acoustic applications for the prototype.

Learners of Underwater acoustic and Transmitter array, this research paper can prove a real asset. One should read bestessays review before help in essays. This research paper was suggested by my mentor to get reliable knowledge on the underwater acoustics.
