Sound fields in and around railway line cuttings are often strongly influenced by reflections between the cutting walls and between cutting walls and train body. The relevance of these reflections was investigated by scale model experiments and by numerical simulations. Based on these findings a semi-empirical calculation scheme was developed that allows for an estimation of sound fields in the surroundings of railway line cuttings. The calculation scheme is designed for easy incorporation into existing engineering railway noise models.
