ANALYSIS OF SELECTED METHODS USED FOR THE REVERBERATION TIME ESTIMATION

The paper presents a comparison of the reverberation time of two boxed rooms considered in two variants. The purpose of the paper is the comparison of the reverberation time measurements results with the results obtained of the available equations and simulation in the ODEON software. The differences between the applicable models and computer simulation and measurement were analyzed. The determined values of the residual analysis were used to develop the rules for granting points to formulas or

STATISTICAL VERIFICATION OF THE REVERBERATION TIME MODELS IN SMALL BOX ROOMS

The paper presents the results of measurements and theoretical calculations for little room models. Five room models have been prepared for analysis and they were placed in a chamber adopted as reverberationless. Measurements of reverberation time in these rooms were made in two variants; first in isotropic sound field, the second in the field disturbed by elements made of mineral wool. Then for all models in both variants theoretical calculations were made by means of three models: Neubeauer

APPLICATION OF THE ANALYTIC HIERARCHY PROCESS (AHP) FOR ACOUSTIC ADAPTATION OF CLASSROOMS

In the paper we put forward a proposition of acoustic adaptation of classrooms based on the analytical hierarchy process (AHP). The main objective of such an adaptation is to increase speech intelligibility aiming to enhance the teaching quality level. The model is based on four main criteria which have impact both on the teaching process and on the adaptation costs. The said criteria comprise reverberation time, speech transmission index STI, financial cost of the adaptation and non-economic
