Abstrakt: This paper describes a part of theoretical and experimental research dealing with the problem of the aeroelastic instability onset of slender rectangular beams [...]

Impedance and wall absorption are important characteristics of acoustical systems. Unlike the electrical case, no convenient commercial system is available for acoustical [...]

Acoustic speech output in humans is commonly considered to results from a combination of a source of sound energy (e.g. the larynx) modulated by a transfer (filter) funct [...]

A Computational Fluid Dynamics (CFD) prediction procedure for computing the internal hydrodynamic behaviour of final clarifiers is presented. Calculations are carried out [...]

We present a Computational Fluid Dynamics (CFD) model that predicts the sedimentation of activated sludge in a full-scale circular secondary clarifier that is equipped wi [...]

Results of a voice numerical simulation using finite element (FE) model of acoustic spaces corresponding to the human vocal tract for English vowel / a / are presented. T [...]

After a short introduction to psychoacoustic parameters evaluation the most common methods of mathematical acoustic modelling - ray tracing and the image source model- ar [...]

The study presents three-dimensional finite element (FE) model of flow induced oscillations of the human vocal folds in interaction with acoustic processes in the simplif [...]

At the loudspeaker system designing, especially for bass zone, many things have be taken to account. First it is loudspeaker, secondary loudspeaker’s baffle board. For [...]
