Why the evaluation of trains need will need to go with soundscapes

초록

To consider the environment of trains under the view of soundscape brings a new perspective in the evaluation of trains and the respective sound quality under scrutiny. The evaluation of soundscapes brings subject-related methodological procedures into this area. With such suitable measurements a way was found that allowed to rely on different dimensions on reaction to these specific environments. Improving the sound quality of an environment imposes not only to reduce loudness but also to account for the qualitative appreciation as a cognitive judgment given by listeners and particularly, for the interaction between acoustic dimensions and other sensory modalities in qualitative judgments of given environments. Getting a better understanding of sound quality in this field requires a multidisciplinary research domain connecting various themes: studies on the subject and his capability in perception and interpretation
