Scale model measurements

In the planning phase, we carry out room acoustic measurements in scaled-down models. These miniature halls rich in detail are created by professional model designers in close correlation with the acoustic requirements on the basis of the architectural plans on a scale of 1:10 or 1:20.

The measurements in the model are performed according to the same method as the measurements in real rooms. However, the sound wavelengths of the measuring signals have to be reduced according to the scale factor of the model, i.e. the measurements have to be carried out at higher frequencies.

Acceptance measurements in the completed hall objectively documents the excellent acoustic relationship.


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.
