The existing body of literature regarding the acoustic design of concert halls has focused almost exclusively on classical music, although there are many more performances of popular music, including rock and pop. Objective measurements were made of the acoustics of 20 rock music venues in Denmark and a questionnaire was used in a subjective assessment of those venues with professional rock mus...

Recent studies on acoustically coupled volumes, worship spaces, and in concert hall acoustics, have prompted an increasing interest in analyzing sound energy decays consisting of more than one decay slope, so-called nonexponential decays. It has been considered very challenging to estimate parameters associated with double-slope decay characteristics, even more challenging when the coupled-volu...

Historically, two equations have been used for predicting reverberation times, Sabine and Eyring. A precise means is presented for determining Eyring absorption coefficients alpha(eyring) when the Sabine coefficients alpha(sabine) are known, and vice versa. Thus, either formula can be used provided the absorption coefficients for the Sabine formula are allowed to exceed 1.0. The Sabine formula ...

This paper presents the spectra of several orchestral instruments measured in the concert hall of the Liceo Statale “Alfano I” in Salerno, Italy. For each musical instrument used the variations of frequency of average signal unweighted (LZeq average) relative to the C diatonic major scale are shown in ascending and descending order. In this study the notes played by eight instruments (flute, tr...

The study of Architectural Acoustics involves the understanding of sound build up and its propagation in a simple room. This knowledge can be further applied to larger rooms and performance areas such as concert halls, theaters and sports arenas. The basic acoustic parameters that govern the quality and intelligibility of sound for the listeners as well as the performers are needed to be evalua...
