Experimental Investigation of the Reverberation Time Inside a Complex Geometry Indoor Space
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 2
Abstract
The paper outlines the interest towards reverberation time which is an acoustic parameter that can influence how a speech is perceived in different parts of a room. If for a rectangular shaped rooms Sabine’s formulas are applicable, for rooms with a complex geometry its applicability is questionable. The purpose of this research is to analyze the acoustic parameter for a room with a complex configuration and to determine the applicability of Sabine’s simplified formula. For measuring the reverberation time multiple points were analyzed using a class 1 precision professional sound meter. For a better understanding of the influence of the reverberation time 2D maps were created. Several comparisons were carried out between the measured reverberation time in this complex geometry room and the reverberation time optimum value, the theoretically calculated value of the reverberation time and the measured values in other rooms from the same building with rectangular shape.
