In times of globalisation, unfortunately, the activities of criminal, extremist and terrorist groups have also increased. The gap between rich and poor is widening. Peaceful coexistence is under serious threat worldwide. There is a clearly increasing readiness to use violence!
Our Institute for Fire Protection and Security Technology has succeeded in developing a highly efficient device. Together with Prof. Dr. J. Herbertz, a pneumatic sound converter was constructed. The system was extensively tested and further developed.
After the death of Prof. Herbertz in 2008, this system was legally protected as a trademark under the project name “Herbertzhorn”.
Today, the system is ready for use with the technical term “long-range means of distance deployment AS2D” (Acoustic System of De-Escalation and Defence).
