Denition of Material Properties in the Acoustical Model Calibration

Document Thumbnail

There are now many commercially available computer programs for predicting acoustics of rooms. All of these computer programs work on the basis of definition of room’s geometry, material properties (mainly the absorption and diffusion characteristics) and definition of the sound source. The results of the calculation are then strongly dependent upon the approximation of these parameters. In this paper, difficulties in the process are indicated and then a methodology for the calibration procedure for ray-tracing software is suggested. The proposed methodology consists of three main items: ‘Absorption-calculator charts’, ‘Diffusion Estimation’ and ‘G-RT graphs’. The mentioned issues of the calibration methodology are briefly discussed and examined by a case study.
