Soundscape and noise observatory of Greater Lyon

Who are we ?

acoucité is a non-profit association created in 1996 by Greater Lyon and its founding members (IFFSTAR, ENTPE, CEREMA, CSTB…). It aims to develop awareness and professional knowledge in urban sound environment.
It is a competence centre intending to promote exchanges between research centres and regional and local authorities, in particular for the management of urban traffic noise.

The association is engaged in the following areas:

  1. Proposition, organization and management of applied research programs and experimental actions together with research centres, industry and local and regional authorities, in order to develop urban techniques using knowledge from research
  2. Assistance to elected representatives and local authorities to face the issues relative to noise in urban and built environments
  3. Organization and follow-up of training courses for professionals of local authorities, through competent and registered bodies
  4. Inventory, publication and dissemination of the knowledge gained and the results of the actions described above

The urban acoustic field requires capabilities from various professions. The action’s area of acoucité covers all of the urban acoustic field and thus allows to gather these capabilities on shared problem.

acoucité contributes to European programs LIFE and Framework Programs 7 and 8 (Diapason, GipsyNoise, Harmonica, Hosanna, Monica…) and animates a network of French and European project partners.

acoucité develops with the ecology service of Greater Lyon a permanent network of noise measurement and monitoring within the urban area.

acoucité is involved in urban design projects in order to master noise levels and promote sound heritage.

acoucité contributes to national programs PREDIT (impact of urban mobility plans on noise).

The association benefits from its human (acoustic engineers et technicians, doctor in psycho-acoustics…) and material resources (6 sound level meters, GIS, acoustic modelling…).
About twenty of works and articles are published each year, often in partnership, on monitoring and assessment of urban traffic noise. They are regularly presented in public during thematic days (day without car, sustainable development, soft transportation modes…), at town request during round tables or during school intervention.
