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.

Calibration of a sound reinforcement

When planning new sound reinforcement equipment for rooms already equipped with such a system one has first to evaluate the actual quality of this existing system.

With the Engineers' Office ADA Acoustics & Media Consultants GmbH planning of acoustic modifications begins therefore on principle with a measurement for capturing the existing acoustic conditions with and without sound reinforcement system. Such electroacoustical measurements are carried out in order to ascertain the transmission quality of the sound reinforcement systems.

Parameters such as reverberation time as well as definition, clarity, articulation loss, sound level distribution, frequency band of the direct sound and the overall sound level and also existing delay and equalizer adjustments, are captured herewith.

After installation of the new equipment has been concluded, the measurements are repeated in the course of project commissioning.

Depending on the problems that had to be solved, the parameters measured with priority are, among others:

  • Sound pressure level distribution
  • Maximum sound pressure level
  • Transmission frequency response
  • Signal travel times
  • STI, Alcons, measure of definition C50, as measures determining speech intelligibility
