The SOPRANOISE project addresses new tools to assess acoustic performances of Noise Barriers (NB) as they are effectively used along road networks.

The Project targets at improving how to assess acoustic performances, not only after NB installation, but also throughout their whole lifetime. The primary aim is to develop innovative quick and safe methods to easily characterize installed NB in-situ, with the clear intention to submit those methods to CEN for standardization.

This research will also provide key information to infrastructure administrators for planning, procurement and lifetime management of NB, mastering how NB reduce noise within a long-term perspective.
