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.

Room acoustic measurements

When planning new room acoustic conditions for existing rooms, the acoustic status to be changed must first be recorded.
Room acoustic measurements are taken to determine the acoustic quality of rooms.

It measures parameters such as:

  • Reverberation time
  • STI, clarity measure C50 as a measure of speech intelligibility
  • Strength G and Center Time as a measure of the level distribution
  • Clarity C80, Objective Support ST1 and Bass Ratio B as measures for music transmission and the like.

The measurements can also be used to draw conclusions about the presence of disturbing echoes and the possibility of their elimination. Likewise, the success of already implemented measures can be determined. The measurement results ​​can be used as the basis for the acoustic simulation program EASE. After the planning has been completed, a control measurement is carried out in an analogous manner.

Measurement tools and instruments:

  • PC-based measurement system EASERA
  • Measurement software EASERA SysTune
  • Sound Level Meter XL2 with STIPa option
  • Measurement loudspeaker dodecahedron
