Introduction
While performing their primary function, road traffic noise reducing devices are exposed to a range of
forces due to wind, dynamic air pressure caused by passing traffic and the self-weight of its component
parts. They can also be subjected to shocks caused by stones or other debris thrown up by vehicle tyres
and, in some countries, the dynamic force of snow ejected by equipment used to clear roads in winter.
The deflections of a noise reducing device under such loads during its design life should not reduce its
effectiveness.
