The project

After a convincing trial installation, the management of the Konzerthaus Berlin has decided to install nine circular “Ignatius- resonators” above the stage of the Konzerthaus.

The optically-appealing membranes of the Ignatius-resonators are formed from a spectrally-tuned, high-quality plastic disc. They are hung over the stage encased in metal frames. Both, their angle and height can be flexibly adjusted. With this, the Konzerthaus Berlin is adjusting to on-site conditions led by the acoustician of MMT Network (www.mmt-network.net) on the basis of simulations and measurements. Said adaption was fine-tuned by chief conductor Iván Fischer.

The result:

The installation of the circular resonators has significantly improved the acoustics of the Konzerthaus Berlin.

In the opinion of spectators the installation of the circular resonators has considerably improved location of instruments, sharpness has been reduced, and the instruments sound softer overall.

According to both, the musicians and the conductors Iván Fischer, Daniel Barenboim and Michael Sanderling, the musicians now hear each other better. Spectators are better connected to the stage. The acoustic effects of the circular Ignatius-resonators have also been praised. In particular, the acoustic radiation of harmonics has improved following the installation. As a result the instruments sound lighter and warmer.
