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.

ADA scope of services:
Room acoustics: similar to HOAI phases
Electroacoustics: similar to HOAI phases 2, 3, 5 - 8 (pre-planning to execution supervision)

Project data:

  • Start of planning: 2005
  • Completion: August 2008
  • Scope of the performed services: approx. 700.000, - EUR

The room acoustics measures aimed at keeping the reverberation time in the empty hall under 3 seconds as far as possible. Extensive absorber surfaces had to be introduced for this purpose, whose location had to be checked by means of computer simulation:

  • Ceiling area through special acoustic mats
  • Wall areas though broadband absorbers behind perforated corrugated metal sheet to protect against damage
  • Absorber pads on ceiling sails
  • Broadband absorber, hung on faces
  • Padded plastic seating

This resulted in reverberation times of less than 2.5 s in the empty hall, which, when occupied (maximum 18,000 visitors), creates an acoustic atmosphere, which also supports classical concerts, but ensures in the same time high speech intelligibility when sound reinforcement systems are used.

The sound reinforcement system in the arena as a standard component of sports events follows a decentralized concept mounted to the roof structure / catwalk. Active loudspeakers with integrated power amplifiers are digitally fed from central control units distributed in the roof space. Exact settings of level and delay times create the impression, that the sound emanates from the middle of the hall, where the large video cube is installed.
