A6B Tunnel

Acoustic efficiency of sound-absorbing tiles and influence on natural lighting.
The civil engineering company for a project to install a partial covering over the A6B motorway asked the CSTB to help optimize the design of the sound-absorbing tiles by means of digital simulation, using the MICADO tool. Several tile configurations were studied, allowing, in particular, the optimization of the slope angle of the boxes.
