Résumé
The aim of this research project is how to actively improve the sound ambience in high-speed trains. Essential aspects are intimacy, a comfortable and enjoyable environment, a coherent sound identity, and the like. There is a need to move beyond conventional noise reduction techniques and modify the way we perceive these environments by employing efforts such as altering sonic composition. This can be achieved by the subtle addition of new sonic components able to divert the attention from the background environment. Two separate routes have been examined here: 1. introducing new sound textures that cannot be distinguished as separate elements in the train environment, "coloring" it in different ways; 2. introducing specific sound textures that will be perceived as subtle but composed added layers.
