Assessing all noise sources in one model. Implementation of INM and ECAC 3rd Edition in Noise Mapping Software

摘要

Legal circumstances, political motivations and technical reasons led in many countries to a separated approach for the calculation, assessment and handling of infrastructure noise caused by road and railway on the one side and the analysis of aircraft noise on the other side. Specific Research efforts analyzing the perception of noise led to guidelines like the German VDI 3722 (Effects of traffic noise/Characteristic quantities in case of multiple sources). Next to other approaches this guideline focuses especially on the annoyance of different noise types and derives a single number value, representing the overall perception of all noise sources, for each affected inhabitant. In order to enable an efficient overall evaluation of noise levels within urban areas, each infrastructural source must be handled within one noise model. The implementation of INM and ECAC 3rd Edition within Noise Mapping software opens various possibilities for an integrated approach to the noise assessment within cities.
