Application of acoustically tuned resonators for the improvement of sound insulation in aircraft [PDF]

open access: yes, 2005
One of the aims of the EU project FACE (Friendly Aircraft Cabin Environment) is to reduce aircraft interior noise. For modern aircraft flying at cruise conditions, the turbulent boundary layer is the main source for cabin noise.

The effect of varying sound velocity on primordial curvature perturbations

open access: yes, 2011
We study the effects of sudden change in the sound velocity on primordial curvature perturbation spectrum in inflationary cosmology, assuming that the background evolution satisfies the slow-roll condition throughout.

Gas flow in barred potentials [PDF]

open access: yes, 2015
We use a Cartesian grid to simulate the flow of gas in a barred Galactic potential and investigate the effects of varying the sound speed in the gas and the resolution of the grid.

Memory for product sounds: The effect of sound and label type

open access: yesActa Psychologica, 2007
The (mnemonic) interactions between auditory, visual, and the semantic systems have been investigated using structurally complex auditory stimuli (i.e., product sounds). Six types of product sounds (air, alarm, cyclic, impact, liquid, mechanical) that vary in spectral-temporal structure were presented in four label type conditions: self-generated text,

Courtyard Sound Field Characteristics by Bell Sounds in Han Chinese Buddhist Temples

open access: yesApplied Sciences, 2020
The acoustic environments of Han Chinese Buddhist temples have long played an important role in the development of Buddhism. This study explored the effects of layouts and spatial elements of Han Chinese Buddhist temples on courtyard sound fields. First,

Temperature dependent sound velocity in hydrodynamic equations for relativistic heavy-ion collisions

open access: yes, 2007
We analyze the effects of different forms of the sound-velocity function cs(T) on the hydrodynamic evolution of matter formed in the central region of relativistic heavy-ion collisions.

Figures Pointing to an End: Operatic Analysis and Modern Sound Design

open access: yesNota Bene, 2013
In a 2003 production of Jean Racine’s Phèdre, the director Patrice Chéreau introduces into the play a bevy of sound effects. The sounds range from solo cello accompaniment to electronically produced crackling noises.

Nonlinear acousto-electric transport in a two-dimensional electron system

open access: yes, 2000
We study both theoretically and experimentally the nonlinear interaction between an intense surface acoustic wave and a two-dimensional electron plasma in semiconductor-piezocrystal hybrid structures.

Underwater sound absorption performance of acoustic metamaterials with multilayered locally resonant scatterers

open access: yesResults in Physics, 2019
Although the conventional locally resonant acoustic metamaterials (LRAMs) have shown better sound absorption performance in the low frequency band, the effective frequency range of the sound absorption performance is quite narrow relatively.

Magneto-elastic waves in crystals of magnetic molecules

open access: yes, 2007
We study magneto-elastic effects in crystals of magnetic molecules. Coupled equations of motion for spins and sound are derived and the possibility of strong resonant magneto-acoustic coupling is demonstrated. Dispersion laws for interacting linear sound
