Research and Development


Organization for Research and Development, our internal resources and our multiple collaboration programs with academic institutions and industry enable us to pursue a systematic policy of R&D in all fields of applied acoustics :

  • acoustic propagation in confined spaces and open areas,
  • acoustic behavior of materials and transmission through a wall,
  • effect of noise on humans and sound environmental management


Applied research :

The list of the main public and private research contracts carried out by the GAMBA Acoustique et Associés group since its inception, shows its ability to work in all the fields of applied acoustics.
