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.

Architectural firm and consultant:
Dar al-Handasah

ADA scope of services:
Computer simulation verification of the planned room acoustics and sound system planning approaches

Project data:

  • Start of work: 2012
  • Completion of individual construction phases: 2013 and 2014
  • on hold since 2015

The room acoustics was verified for more than one million additional pilgrims. The proposed loudspeaker positions were modelled in very complex computer models and in all so-called "prayer halls" the achievable speech intelligibility was verified, and if necessary the settings of the digitally controlled line arrays were modified by the manufacturer Renkus-Heinz.

More than 3,000 loudspeakers and line arrays can all be addressed by the Imam‘s central microphone, for which a new signal distribution network was planned by the consultant and worked out by by ADA.
