Acoustic waves are fascinating phenomena in gases, liquids or solids with numerous
physical and technical aspects. Air is the medium of interest when it comes to audible sound …

Part of this work was presented in “Influence of scattering coefficient on the prediction of
room acoustic parameters in a virtual concert hall through three different algorithms” …

This paper proposes an evaluation procedure using a scale model to assess the noise
reduction effects of vegetated façades for sustainable urban building designs. The …

Diffusive surfaces should be optimally designed for acoustic and aesthetic purposes.
Fractals are commonly used to adapt to the parametric demands of interface design …

Scattered sound fields in an opera house were objectively and subjectively evaluated
through acoustical measurements in a 1: 10 scale model and through auditory preference …

The effects of wall diffusing elements on sound-field diffuseness were investigated in a tenth-
scale model hall and in a real recital hall. Acoustical measurements were carried out in both …

This paper presents the effects of height and coverage density of diffusive surfaces through
the measurements of scattering and diffusion coefficients using scale models …

The experimental results presented in this study aim at providing an useful insight into the
accuracy of the measurement procedure of the random-incidence scattering coefficient as …

In musical or theatrical performance, some venues allow listeners to individually localize
and segregate individual performers, while others produce a well blended ensemble sound …

This paper proposes a new design of an acoustic diffuser based on the construction rules of
the Sierpinski triangle in order to broaden the effective diffusion frequency range. The …
