Meaning

Noise predictions following the state of the art are impossible without computer programs. As long as typical noise situation involving traffic noise or industrial noise is concerned, reliable sotftware suite can be applied which conduct the prediction and assessment according to relevant standards and guidelines.

Beyond the State of the Art

In special noise situations the standard software is not sufficient. For example, if explosions come into play prediction schemes fail to yield reliable results. Particular estimations are needed.

This also holds for noise from wind turbine noise. In Germany, the sound levels from these source are predicted using the scheme of ISO 9613. However, the replacement source for wind turbines have such great altidudes that this standard is not applicable because the ISO 9613 does not hold for high sources. In addition, the scope of the ISO 9613 excludes literally the application of its prediction scheme to shooting noise.

Management Software

Cervus is the contact for dedicated software in such cases. Dr. Hirsch und  Frank Hammelmann developed for instance the prediction software WinLarm that is used by the Bundeswehr to predict and assess the shooting noise from large and medium caliber weapons. Only to give one particuler clue; WinLarm comes with round about 7000 different shot configurations (i.e. different weapon systems, weoapons and ammunition combinations) having different source stregth and directivity. These number makes clear that it not only a prediction scheme that makes shooting noise special. There is a need for databases and programs to maintain and store the data.

Hence, modern co-operative noise management is a dedicated process designed to be part of the daily operation of the military training facilities. It needs sophisticated procedures to find a fair ballance between the unavoidable shooting noise the also unavoidable miltary training.
