Summary:
This work summarizes our efforts to consult the Deutsche Oper Berlin throughout the implementation of the European directive 2003/10/EC. The directive stresses the reduction of noise related risks at their point of origin. In terms of an opera house, we therefore look at the design of the orchestra pit. The pit must support the projection into the hall as well as the hearing between orchestra sections. Moreover it has to be a stimulating and comfortable work environment. Importantly, room acoustic solutions of tempering sound pressure levels in the orchestra pit must not influence the excellent room acoustics of the opera house. \n\nFor this reason sound pressure levels during performance were measured in parallel with room acoustic parameters. These measurements describe the current state of the opera widely and allow for a comparison with the intentions and investigations of Cremer et al. from the year 1962 during the construction phase. Secondly, the results of the measurements serve to adjust computer simulation models, which were subsequently employed to assess room acoustical alterations. \n\nLiterature shows that improved acoustic contact among musicians in the orchestra pit can lead to reduced sound pressure levels without compromising on dynamics. A primary goal of this project is therefore to increase the mutual audibility of musicians through a differentiated sound transparency in space and time. The presented results give first indications of possible solutions.
