```
public class TramwaySchall03
extends Object
```
Compute sound emission levels of tramway sound source The proposed model is a very simplified version, inspired by : Moehler, U.; Liepert, M.; Kurze, U.J.; Onnich, H. The new German prediction model for railway noise 'Schall 03 2006'. In Noise and Vibration Mitigation for Rail Transportation Systems; Springer: Berlin, Germany, 2008; pp. 186–192.
