TLDR
In this article, the damping constants of resonant bubbles are extended to the off-resonance case and it is shown that thermal damping is important for bubbles driven below resonance, and radiation damping for those above resonance.Abstract:
Results obtained by Devin [J. Acoust. Soc. Amer. 31, 1654–1667 (1959)] for the damping constants of resonant bubbles are extended to the off‐resonance case. Calculated results show for the range of conditions considered that thermal damping is important for bubbles driven below resonance, and radiation damping is important for those above resonance.read more

Ultrasound contrast agents : optical and acoustical characterization
TL;DR: In this paper, the authors describe the characterization of the dynamics and the acoustic responses of single BR14 (Bracco Research S.A., Geneva, Switzerland) ultra-sound contrast agent microbubbles under the in°uence of ultrasound.

General Characteristics of the Underwater Environment
L. Bjørnø,Michael J. Buckingham +1 more
TL;DR: In this paper, a brief history of underwater acoustics from the time of the Greek philosopher Aristotle up to the post-World War II era is presented, with a discussion of the international system of units used in the book and a discussion on the use of the decibel scale.

Generation and In Situ Electrochemical Detection of Transient Nanobubbles
TL;DR: The possibility of stable nanobubbles in the bulk remains in question as discussed by the authors, although there is strong evidence for the existence of surface bound nanobbles, the possibility remains in doubt.
On the characteristics of sound generated by bubbles injected underwater
TL;DR: In this article, the transient oscillation of an air bubble injected underwater is investigated, and the results show that these bubbles can generate a sufficiently strong acoustic signal that can be utilized for passive remote sensing.

Specifying spectra for musical scales
TL;DR: In this paper, a symbolic method for constructing related spectra for scales built from a small number of successive intervals is presented. But it is not clear how to find related spectrum for a given scale.
