Scale Model measurements
We carry out acoustic measurements using reduced scale models during the planning phase. Professional model makers make these detailed miniature rooms in strict accordance with the acoustic specifications based on the architectural plans on a scale of 1:10 or 1:20.
Measurements taken using scale models are done according to the same method as measurements taken in actual rooms. However, the sound wave lengths of the measurement signals have to be reduced by the scaling factor of the model, which means that the measurements are carried out at higher frequencies. In a model built on a scale of 1:10, sounds such as the standard pitch A sounds like this (Sample).
Model measurements have an advantage compared to computer simulations, in that the transfer takes place true to the wave nature of the sound, that means that acoustic focus and sound scattering patterns are very well mapped. Because of the specific advantages and disadvantages of both model measurements and computer simulations, Müller-BBM often uses both methods for the most demanding acoustical plans for concert halls and opera houses.
Often, the model later finds a worthy place to be displayed - in the entrance hall of the finished building, for example.
