, 2015 The volume of air that goes in and out of a musical instrument's sound hole is related to the sound hole's contribution to the volume of the sound. Helmholtz's result for the simplest case of steady flow through an elliptical hole is reviewed. Measurements on multiple holes in sound box geometries and scales relevant to real musical instruments ...

Osong Public Health and Research Perspectives, 2014 Can you remember your old schooldays? For some reason, we remember the old good days as being especially beautiful. All the shrubs on campus were in blossom and the trees were green. The grass was dotted with dandelions. Everyone was happy and carefree, for the vacation was just about to begin. With that to look forward to, no-one was worried about the

, 2020 The chapter addresses compositional strategies in works by Arvo Pärt unifying his different creative periods. The impetus of early Flemish polyphony, which is present in the Symphony No. 3 (1971) and in the first tintinnabuli pieces (1976) is predicted in some of his earliest compositions: Pärt sought equality between the horizontal and vertical ...

An attempt was made to determine the presence of scattering resulting from the nonlinear interaction of two finite-amplitude sources, operating in water. Experiments were performed with two beams crossed at right angles and also in the nonperpendicular case, A detector crystal, tuned to the summation frequency (13.4 Mc) of the two sources (7.4 Mc and 6.

On modulation of sound by sound
Journal of Engineering Physics and Thermophysics, 1997Frequency shifts of continuous acoustic waves propagating in a medium which arise due to the effect of external acoustic disturbances arbitrarily propagating in the same medium are analyzed. An analytical dependence of the magnitude of the acoustic shift on the angle between the wave vectors of the probing and external waves is obtained.

The exact solution for first order nonlinear scattering of two plane waves of sound [J. Acoust. Soc. Amer. 29, 934 0957)] showed the scattered density to be ρs = c0−2E12+12ω1−1ω2−1(cosθ+12Λ)[sin−2(12θ)]∇2W12. The singularity at θ = 0, which occurs when the primary waves are collinear, may be removed by applying to this solution the operator {1 − exp[(|∂
