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.

Planning a voice alarm system (SAA) in the station building
Room acoustics and electroacoustics

ADA scope of services:
Acoustic sound certificate for the installation of a SAA

Project data:

  • Start of planning: 2016
  • Completion: 2017

The public address system was renewed in all public areas of the station building in compliance with the requirements of voice alarm systems according to DIN VDE 0833-4. Particularly noteworthy is the lobby. This has a very sophisticated room acoustics and is subject to monument protection beacause of elaborate, old murals. Here very different loudspeaker types and arrangements were tested by computer simulations. With a usual noise level assumption of 75-80dBA, no success could be achieved. A 24-hour measurement with data loggers resulted in a mean level of only 65dBA, under which the necessary speech intelligibility values ​​STI could be realised.
