Acoustical Testing of Auditorium Models With the AId of the Midas Package

l tu'rmmtmAcoustic modelling is a valuable technique enabling an auditorium design to be investigated and modified at an early stage of development.The behaviour of sound in the auditorium and the acoustic characteristics of the design can be investigated and predicted by investigation of a scale model of the auditorium.This enables the architect to ensure that no major design faults mill be encountered after the auditorium has been built.although acoustic modelling is of great value to the architect, current traditional model testing techniques have the disadvantages of relatively high costs and long model preparation and testing times.A recently developed set of computer programs known as the Midas Package enables cheaper models to be used and testing times to be shortened.This paper briefly describes the Midas Package and experience gained by the author in the use of the package for testing 1:50 scale auditorium models.
