Noise Impact Assessment in LCA:

Damage Function of Road Transport Noise in Japan

Abstract

Road transport noise has been hardly assessed in LCA studies so far despite its nationwide significance. It is not included in the impact categories covered in most of current LCIA systems such as LIME (Itsubo et al., 2005). In this study, we developed the damage function of road transport noise based on the framework proposed by Muller-Wenk (2004) and calculated the damage factors by applying Japanese environmental data and models. Our damage factors are smaller than the Swiss factors by Müller-Wenk mainly because of the different traffic situations and the adopted dose-response relationships.
