ADA Acoustics & Media Consultants GmbH

After the defeat of the German division, and upon meeting the objective requirements, the engineering firm ADA Acoustic Design Ahnert was initially founded with two colleagues. From day one, the software program EASE, which was at that time still DOS-based, was available. As a result, the feasibility of room- and electro-acoustic designs could be efficiently verified. Large projects during the early 90s, such as the planning of a new sound reinforcement system for the German Opera (Deutsche Oper) in Berlin, supported the start-up phase.


A similar experience was gathered during the reconstruction of the Plenary Assembly of the Parliament in Ankara, where in 1996, for the first time, a fingerprint system for the identification of the Members of Parliament was introduced, which is still in operation in its original form till today. The number of awarded contracts in the country and abroad was then increasing as well as the number of employees. In 2010, the activities profile of the sole-property company ADA Acoustic Design Ahnert was transferred to ADA Acoustics & Media Consultants GmbH. Major tasks are still ahead of our team, such as the extensive Al Maktoum International Airport, which is currently under construction and is intended in its first construction phase to serve around 120 million passengers per year.

National Opera Bucharest, Romania

Bucharest in Romania 2013-2015

Room Acoustics
Renovation / Alteration


Client:
ONB Bucharest

Architects of the reconstruction:
Radu Pana and Marius Smigelschi

Project Description:
The historic building of the National Opera Bucharest suffered from too dry and generally shortcoming room acoustics.
The conditions for the musicians in the orchestra pit were also very bad in terms of mutual listening.
To improve the acoustics, therefore, a major renovation was carried out, partly with alterations in the orchestra pit.

The acoustic task was basically to significantly improve the acoustic properties of the hall through the replacement of absorbtive surfaces (ie carpet, fabric wall coverings, etc.) by reflective materials (wood paneling, new stalls design).
After extensive investigations (measurements and simulations) an increase of the reverberation time by 0.2-0.3 s to actual values ​​of about 1.3 to 1.4 s was finally achieved.
Also the very high clarity (typical for speech theater by + 5 ... 6dB) could be reduced to values ​​of 0 ... + 2dB for the opera performances.

Together with the changes in the geometric situation in the pit, the acoustic characteristics of the hall for musicians, singers and the audience are now very satsifactory.
