  Urban noise maps and noise visualizations traditionally provide macroscopic
representations of noise levels across cities. However, those representations
fail at accurately gauging the sound perception associated with these sound
environments, as perception highly depends on the sound sources involved. This
paper aims at analyzing the need for the representations of sound sources, by
identifying the urban stakeholders for whom such representations are assumed to
be of importance. Through spoken interviews with various urban stakeholders, we
have gained insight into current practices, the strengths and weaknesses of
existing tools and the relevance of incorporating sound sources into existing
urban sound environment representations. Three distinct use of sound source
representations emerged in this study: 1) noise-related complaints for
industrials and specialized citizens, 2) soundscape quality assessment for
citizens, and 3) guidance for urban planners. Findings also reveal diverse
perspectives for the use of visualizations, which should use indicators adapted
to the target audience, and enable data accessibility.
