Consulting, design and measurement of loudspeaker systems according to DIN VDE 0833-4 and DIN EN 50849

For many public buildings, voice alarm systems in accordance with DIN VDE 0833-4 or DIN EN 50849 are mandatory. We design such systems by computer predictions to confirm that the required speech intelligibility can be provided even before the building is completed. We also assist in designing any necessary room acoustic treatment and undertake the commissioning, optimisation and programming of voice alarm systems on site–anyhwere in the world. For measurements according to DIN EN 60268-16:2012-05 we are accredited according to DIN EN ISO/IEC 17025:2018, Jakob Kraft is “responsible person for voice alarm systems” according to DIN 14675 -1.

In Berlin, Potsdam and Brandenburg we also supply turnkey sound reinforcement systems for churches, conference and seminar rooms and much more.
