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.

Citizen Hall (Bürgersaal) in Town Hall Spandau

Spandau - Germany 2017 - 2018

Renewal of public address systems

District office Spandau of Berlin

Planning scope ADA:
Rescheduling of the sound system in the historical stock while avoiding a building construction measure by integrating the existing cabling and maintaining the old positions for loudspeakers and the central device rack

Project data:

Planning start: 11/2017
Completion: 09/2018
Scope of services performed:
A new sound system had to be planned for the citizens' hall in the Spandau town hall in Berlin. The sound quality and the technical possibilities of the old system were judged to be poor. When planning the new building, the historical structure of the building had to be taken into account, which means that accompanying building construction measures had to be completely ruled out as part of the implementation of the new sound system. For example, to avoid additional cable routing in the hall, e.g. by the old speaker positions, the existing lines and the position of the central device rack have been retained.

The Citizens' Hall has a floor area of ​​approx. 215 m² (including a podium), and a height of 7.6 m results in a room volume of approx. 1,660 m³. The hall is equipped with upholstered armchairs (172 seats) along with podium furniture (tables, chairs, lectern). The sub-optimal room acoustics in the hall made it necessary to have a sound system based on DSP-controlled, active loudspeaker lines, which were also to be controlled via the existing and reusable 2-core cables. The central device rack to be equipped and configured now includes up-to-date import and recording options and is operated via a user-specific interface by calling up implemented presets for various usage scenarios.
