We present an acoustic rendering approach visualizing the listener-specific contribution of frequency-dependent pressure fields on a scene geometry with acoustic reflection and scattering properties. Our method facilitates the evaluation of simulated acoustics showing the effect of simulation parameters like absorption and scattering. The image-based spatial localization of acoustic properties ...

The spectral and modal properties of the vocal tract are important acoustic characteristics since they take part in generating the formants of individual vowels. The positions of vowel formants on the spectrum frequency axis are mainly determined by the parameters and properties of the vocal tract : its size and geometry, boundary conditions ( opening mouth and glottis, closing ) and absorption...

The potential of tree bark, a by-product the woodworking industry, has been studied for more than seven decades. Bark, as sustainable raw material, can replace wood or other resources in numerous applications construction. In this study, acoustic properties bark-based panels were analyzed. roles particle size (4–11 mm and 10–30 mm), orientation (parallel perpendicular) density (350–700 kg/m3) s...

1- introduction this research attempts to investigate the effects of forensically-relevant facial concealment on voiceless fricatives /f, s, ʃ/ in farsi. there are various types of face-concealing garments that are commonly worn by people for the occupational, recreational, religious, and cultural purposes .these coverings may be typically used as disguises during the commission of crime by del...

Previous research has shown that analog mapping of information unto acoustic properties of speech can affect listeners’ interpretation of described objects and events. In this paper, we examine whether the effect of analog acoustic variation on listeners is governed by intrinsic acoustic properties of the stimulus, through direct priming of listeners’ concepts or behavior. For example, fast spe...
