However by virtue of their directive properties, HOSs may be driven to not only avoid the creation of excess reverberation but also to use room reflection to contribute constructively to the desired sound field. The manner by which the loudspeakers steer the sound around the room is determined ...
As the pitch of the sound increases, what happens to the frequency?Two waves traveling on a string in the same direction both have a frequency of 100 Hz, a wavelength of 2 cm and an amplitude of .02 m. What is the amplitude of the resultant...

The subject of the research presented in the article was the modelling of acoustic properties of two-layer baffles, used in vibroacoustic protection. Baffles of this type are used, among others, in the construction of walls of the sound insulating enclosures of machines and devices. The ...
论文与出版物 The properties of the sound wave propagating in a superfluid two-phase system (liquid helium and its vapor) are investigated. At a frequency sufficiently low so that the superfluid helium and its vapor are in quasistatic equilibrium, there can propagate only one sound mode whose wa...
Objectives: (1) To develop a two-level poroelastic homogenization model that relates the composition and elastic properties of sound and caries affected dentin, and (2) to compare the model calculations with experimental data from scanning acoustic microscopy (SAM). Methods: Elastic modulus of a se...
$40 Mondo is proud to present the soundtrack to Laika's fourth animated feature: KUBO AND THE TWO STRINGS. Composed by Dario Marianelli (THE BOXTROLLS), and featuring an incredible cover of George Harrison's classic "While My Guitar Gently Weeps" by the inimitable Regina Spektor. ...
