摘要

In Helsinki, a new theatre building was completed in 1860. The building became known as Nya Teatern, 'the New Theatre', as it replaced the earlier wooden theatre building. The new theatre building was expected to become a stage for drama, opera and orchestral music. It also became the first Finnish building which was a discussion topic because of its acoustics. Already its building plans were criticized, and newspapers wrote critically about the completed building. The architect responsible for the design also participated in the discussion and explained the design principles of the building. Contemporary opinions say that the acoustics of the theater considering music was a disappointment and that there were many seats that had very poor audibility. Only three years after its inauguration, the theater burnt down. Nowadays it is not possible to listen or measure its acoustics. However, the building plans still exist, which makes it possible to model the acoustics. The aim of this study was to compare the results of room acoustic modelling with the contemporary opinions on the theatre. According to the modelling, theater's reverberation time was short, 0,8 at mid-frequencies. For drama purposes, the theater's acoustics was fairly good in many seats, but for opera and orchestral music it was not very suitable. By acoustic modelling, large differences between the seats could be found which was expected on the basis of the contemporary opinions. At the upper circle, there were several seats that did not have any visual contact with the stage. Thus, the acoustic modelling verified the contemporary opinions.
