Model measurements

Scale Model measurements

[Translate to English:] In der Planungsphase führen wir raumakustische Messungen in maßstäblich verkleinerten Modellen durch. Diese detailreichen Miniatursäle werden von professionellen Modellbauern in enger Abstimmung mit den akustischen Vorgaben auf Grundlage der architektonischen Pläne, im Maßstab 1:10 oder 1:20 gefertigt.

Die Messungen im Modell erfolgen nach der gleichen Methode wie die Messungen in realen Räumen. Die Schallwellenlängen der Messsignale müssen dabei aber um den Maßstabsfaktor des Modells reduziert werden, d.h. die Messungen erfolgen bei höheren Frequenzen.

Model of a chamber music hall scaled to 1:10 in order to study the acoustic behaviour of the complex wall structures
Acceptance measurements in the completed hall objectively documents the excellent acoustic relationship.

[Translate to English:]

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.
