Sound Control has vast experience in design and fabrication of large scale Tunnel Ventilation Attenuation projects. Transport tunnels are frequently located in urban areas with noise sensitive requirements.

Our designs provide suitable attenuation for both inlet and discharge portions of the tunnel ventilation project. Knowledge in design and manufacture has led Sound Control to the development of large splitter assemblies for installation into tunnel shafts and plenums.
