The main hall where meetings are held previously suffered from relatively high reverberation times, with large windows and solid surfaces leading to poor intelligibility for members. The administrative office issued a mandate to consultants Akustikbüro Krämer & Stegmaier GmbH, whose job it was to find a solution to the problem.
Krämer & Stegmaier knew that digital beam-steering would solve the issue at the Mid-Berlin town hall, and were contemplating using a particular brand that they had tried before. They were then approached by Gerd Thielemann (general manager & project engineer from Systemintegration Berlin), who informed them about the positive experiences he had when working with Tannoy's award-winning digital beam steering range, QFlex.
With all the data available, the designers of Krämer & Stegmaier simulated different approaches
with CATT-Acoustic. Based on the results the decision was made to go with the most effective solution - the QFlex 24. The QFlex are used in an arrangement with three Kling und Freitag CA 106 for monitoring. The STI- measurements made after the installations were 0.63 and 0.72, putting it very high on the intelligibility scale.
Gerd Thielemann said, "Tannoy's QFlex is performing excellent in the space. The hall has a lot of glass and reverberant surfaces, and the precise beam-steering technology available from Tannoy allows us to avoid reflections."
