“…The thermoradiational (or thermoacoustic) mechanism of sound wave generation (due to energy released from particles) is the most studied. This effect also was explored in ITEP and obtained results have confirmed the prevalent contribution of thermoacoustic mechanism in water at temperatures different from 4 1C [4][5][6]. Along the thermoacoustic phenomena other mechanisms of sound generation from high-energy particles are also widely discussed.…”

“…The thermoradiational mechanisms (also called as thermoacoustic, thermoelastic one) of sonic waves generation from high energy particles is the most investigated at the accelerator and lasers experiments [3][4][5][6][7][8][9]. Acoustic waves generation in the water from proton beam (Ep =125 and 200 MeV) with duration of the beam spill-out of 70 ns was investigated at the ITEP synchrotron, that confirmed the prelevant yield of thermoradational mechanism to sound arising.…”

Abstract. The experiment on search of acoustic phenomena from EAS was carried out in the scheme of the trigger start from the scintillation installation. Two methods were developed for search of weak ultrasonic pulses from showers: method of peak and noncoincidences and method of small peaks. The results (obtained from different hydrophones) at very different noises and geometries point at the registration of acoustic effects from showers.

The generation of hydrodynamic radiation in interactions of pulsed proton and laser beams with matter is explored. The beams were directed into a water target and the resulting acoustic signals were recorded with pressure sensitive sensors. Measurements were performed with varying pulse energies, sensor positions, beam diameters and temperatures. The obtained data are matched by simulation results based on the thermo-acoustic model with uncertainties at a level of 10%. The results imply that the primary mechanism for sound generation by the energy deposition of particles propagating in water is the local heating of the medium. The heating results in a fast expansion or contraction and a pressure pulse of bipolar shape is emitted into the surrounding medium. An interesting, widely discussed application of this effect could be the detection of ultra-high energetic cosmic neutrinos in future large-scale acoustic neutrino detectors. For this application a validation of the sound generation mechanism to high accuracy, as achieved with the experiments discussed in this article, is of high importance.
