Environmental noise is a major concern for our fellow-citizens. Various tools are used concerning environmental noise management. Among them, noise maps, obligatory since the adoption of European directive 2002/49/EC, aim at representing the mean acoustical state of a given area, using the energetic index Lden. The limits of such indices were highlighted in previous studies, especially when it comes to linking it to noise annoyance. In this context, this work aims at contributing to the improvement of noise maps by the proposal of noise annoyance acoustical indicators, relevant from the individual point of view, for road traffic noise in isolation and combined with industrial noise. In this aim, this work is divided into 3 steps: (1) physical and perceptual characterization of urban road traffic noise for the proposal of noise annoyance indicators, (2) physical and perceptual characterization of combined road traffic and industrial noises for the proposal of total annoyance models, and (3) confrontation of the results obtained through the previous steps to the data of an experiment led in a simulated environment, and to the data of a noise annoyance survey.
