Abstract (sommario):
Researchers have devised a new technique to use sound waves, opening the way for simple acoustic compressors, speedy chemical-process reactors, and clean electric-power generators. MacroSonix Corp. in Richmond, Vermont, has developed a technique by which standing sound waves resonating in specially shaped closed cavities can be loaded with thousands of times more energy than was previously possible. Company’s wave-shaping technology is known as resonant macrosonic synthesis (RMS). With some clever engineering, he said, the elevated acoustic-energy levels produced using RMS can be tapped for a

Sound waves affect plants at the biochemical, physical, and genetic levels. However, the mechanisms by which plants respond to sound waves are largely unknown. Therefore, the aim of this study was to examine the effect of sound waves on Arabidopsis thaliana growth. The results of the study showed that Arabidopsis seeds exposed to sound waves (100 and 100 + 9k Hz) for 15 h per day for 3 day had significantly longer root growth than that in the control group. The root length and cell number in the root apical meristem were significantly affected by sound waves. Furthermore, genes involved in cel

Abstract (sommario):
A parametric array loudspeaker can achieve sharp directivity in the audible band by utilizing ultrasounds. Ultrasounds are emitted intensely from the parametric array loudspeaker and the difference frequency component self-demodulates due to the nonlinear interactions in the air. Therefore, the sound pressure of the audible sound reproduced by the parametric array loudspeaker is lower than that reproduced by the conventional electro-dynamic loudspeaker. This makes it difficult to use the parametric loudspeaker in a noisy environment. To solve this problem, we modify conventional modulations to

Abstract (sommario):
The Landau damping of sound waves in a plasma consisting of ensemble of magnetic flux tubes is discussed. It is shown that sound waves cannot be Landau damped in general but under certain restricted conditions on plasma parameters the possibility of absorption of these waves can exist. The possibility of radiative damping of the acoustic waves along the magnetic filaments is also discussed. It appears that the most plausible mechanism of damping of sound waves in a plasma consisting of magnetic filaments can be due to scattering of a sound wave by the filaments.

In recent years, high-intensity airborne ultrasonic waves applied technology has been developed actively. Accordingly, there are concerns about the effects of sound wave exposure by high-intensity airborne ultrasonic waves. The sound wave intensity is different near the entrance of the ear canal and near the eardrum, because the wavelength is short in the ultrasonic region. Therefore, it is necessary to know accurately the sound pressure at the eardrum position in considering the effects of sound waves exposure by ultrasonic waves.

Abstract. Short wavelength ion sound waves (2-4kHz) are detected in association with the Langmuir waves (~15-30kHz) in the source regions of several local type III radio bursts. They are most probably not due to any resonant wave-wave interactions such as the electrostatic decay instability because their wavelengths are much shorter than those of Langmuir waves. The Langmuir waves occur as coherent field structures with peak intensities exceeding the Langmuir collapse thresholds. Their scale sizes are of the order of the wavelength of an ion sound wave.
