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.

Electroacoustics: preliminary planning to execution supervision

Project data:

  • Study, preconception 2010
  • Start of planning: 2013
  • Completion: August 2014
  •  Scope of services performed: approx. 1025000 EUR

The plenary hall of the Grand National Assembly of Turkey had been completely renovated in the years 1996 - 1998 as planned by ADA.

First, in a study for the responsible technical department of the building, the need for the renewal of the conference and audio systems, as well as the related display / presentation systems was pointed out.

As a first step, the sound reinforcement system was completely replaced. The main loudspeaker systems are now based on line arrays, which are acoustically supported for the large visitor's gallery with other smaller subsystems. A new localization system has been created over the deputies' seats, which can now be perceived from four zones according to their place. New digital mixer console, and an accordingly large extended audio matrix with a new higher-level control system complete the installed system.
