“…[7][8][9] Understanding the behavior of single bubbles is fundamental to the study of collections of bubbles in any of these applications. Recently, the behavior of bubbles confined in tubes or channels and near surfaces has become important for medical and industrial applications.…”

Although deviations in the measurement of acoustic parameters should be lower than the subjectively perceivable change in the corresponding parameter measured, this study reflects that directionality of sound sources could cause wide audience areas to break away from this criterion at high frequencies, even when using dodecahedron loudspeakers which meet the requirements of the ISO 3382 standard. The directivity of four different acoustic sources was measured and the influence of its accurate orientation spatially quantified in five enclosures for speech and music. By means of simulation software, the number of receivers affected by uncertainties greater than difference limens was established.

“…Furthermore, they suggest that shock dynamics is responsible for the damage to surfaces and the generation of noise observed in many cavitating flows. Within the medical application of shock-wave lithotripsy these high pressure pulses are used to destruct kidney stones, see Ikeda et al [103]. Johnson et al [107] investigated this phenomenon numerically.…”

“…While the use of HIFU in lithotripsy is relatively recent (Ikeda et al 2006;Yoshizawa et al 2009;Duryea et al 2011;Harper et al 2014;Maxwell et al 2015), it has some significant advantages over SWL. HIFU can be focused much more precisely than shock waves such that it can enhance the damage at the desired site while reducing collateral tissue damage.…”

“…HIFU can be focused much more precisely than shock waves such that it can enhance the damage at the desired site while reducing collateral tissue damage. Cavitation is also an important factor in HIFU lithotripsy, and the cavitation generated at the focal point pulverizes the stones, ultimately reducing them to powder (Ikeda et al 2006).…”

“…They proposed a two-frequency combined waveform method to concentrate very high pressures on stone surfaces within the localized cavitation area, and they utilized the collapse of a cavitation cloud to fragment the stones (Yoshizawa et al 2009;Matsumoto et al 2005;Ikeda et al 2006). Figure 5.29 shows a schematic of their cavitation control lithotripsy (CCL) method.…”
