摘要

The old building of the theatre was rebuilt for several times during XIX-XX centuries. The interior of the hall had been totally lost before the last reconstruction. The architectural team decided to restore the initial historical view of the hall. It was designed in a classical style with a horseshoe-like plan of the stalls. There were a dress-circle and 3 rows of curved balconies. The upper balcony was used for the placement of lighting equipment and did not include any seats for the audience. The total capacity of the hall was rather small and equal to 310 seats placed in the stalls, the small dress-circle and 2 rows of balconies. The computer simulation was used for the acoustic design. The target value of RT=1.1 s was proposed. The sound absorbing materials were not used. The walls and the ceiling were mainly covered with plaster and wooden panels. The fronts of the dress-circle and the balconies were made of multilayer plywood and had a curved form. Acoustic measurements were done in the hall after the end of the reconstruction according to ISO 3382. The analysis of the results as well as the subjective estimation leads to the conclusion of a good sound quality in the hall.
