The historical heritage building of the National Opera Bucharest suffered from too dry and generally disadvantageous room acoustical properties. Additionally, the musician’s mutual hearing conditions were poor within the orchestra pit. ADA-AMC was commissioned to lead an acoustical renovation and alteration of the hall.
The main acoustical task was to increase the room’s reverberation time significantly by substituting absorptive faces (such as carpet, fabric wall linings, etc.) by reflective materials. After an elaborate study, including extensive site measurements and simulations an increased reverberation time of plus 0.2 … 0.3 s was reached to get to new reverberation times of about 1.3 to 1.4 s. In combination with geometric modifications concerning the pit, the acoustical properties of the hall are now very satisfying for musicians, singers and the audience.
