Roomacoustic planning methods
<<< back	For remodeling existing halls one starts necessarily with an evaluating measurement and with a check-up of available documents and finishes with a descriptive documentation. With large projects there ensues the cooperation with the architect resulting in first designs which are then pending for assessment, also regarding their acoustic quality. For enhancing planning reliability of the acoustic elaboration, the so-called model measuring technique was conceived in the 20s and 30s of last Century. This technique was received with such a response that it soon became developed to highest perfection. The room to be planned is herewith reproduced in a model of wood or plaster to a scale between 1:10 and 1:40, in which sound propagation is measured by means of miniature transmitters and receivers. Nowadays this role has largely been taken over by computer models. These have the additional advantage of allowing to vary and test the inclination and orientation of walls and ceilings as well as the acoustic properties of these surfaces.
