Noise pollution is considered as one of the most annoying factors in educational and office environments. In these environments where learning processes and intellectual activities are ongoing, an effective acoustic design is necessary. The aim of this paper is to assess the reverberation time as one of the important indicators in describing the acoustic characteristics of rooms. In this study,...
worship places are psychologically evolved in human’s mind, because his unconscious mind manifests evolution differently in such places. every religion has its concerning style, while islam and christianity represent two different blazes in two separate places. church and mosque are very important worship places and designers try to create a spiritual sense of place for the audience. whereas ac...
Introduction: The previous studies have used fibrous absorbents usually in the form of cone-shaped wedges for making anechoic and semi-anechoic chambers which their design and construction have been costly and difficult. The present study aimed to design a semi-anechoic chamber, using rectangular fibrous absorbents and also perform acoustic analysis for it. . Material and Method: In the presen...
The measurement of short reverberation times poses different problems depending at the same time on difficulties of measurement and the sensitivity of the analysis techniques applicable to short signals. This article presents a toolbox, which allows a reliable estimation of reverberation time for small spaces, in a software environment, and using a lightweight system, designed for in-situ measu...
Reverberation enhances music perception and is one of the most important acoustic factors in auditorium design. However, previous research on reverberant music perception has focused on young normal-hearing (YNH) listeners. Old hearing-impaired (OHI) listeners have degraded spatial auditory processing; therefore, they may perceive reverberant music differently. Two experiments were conducted ex...
