One of the aims of Cart_ASUR project is to propose an indicator of urban sound quality based on perceptive and acoustic data. The originality of this project consists in using mobile phone technology to collect data. 60 persons had to assess about 20 locations in Paris at four or five homogenous periods (days, evening, night, summer, winter) with a specific questionnaire through mobiles. In the questionnaire, the first questions are related to global sound environment characterization with semantic scales. The next questions concern the perceived loudness assessment of some emergent sources (light vehicles, trucks, bus and mopeds). Finally, the last questions deals with the presence time ratio assessment of sources that do not emerge from the background (birds, voices, steps, etc). Before each assessment, sound pressure level is recorded each second from the mobile phone’s microphone during a 10-minute period. In this paper, the link between global sound quality and loudness assessment of emergent sources is developed. A particular attention is devoted to the situation classification. Depending on the type of location, some identified sources have an influence on the sound quality of the environment.
