This paper reviews ways of reducing surface transport noise by natural means. The noise
abatement solutions of interest can be easily (visually) incorporated in the landscape or help …

The second edition of Predicting Outdoor Sound is an up-to-date reference on the
propagation of sound close to the ground and its prediction. New content includes …

Low-cost airlines have significantly increased air transport, thus an increase in aviation
noise. Therefore, predicting aircraft noise is an important component for designing an aircraft …

Growing demand on transportation, road and railway networks has increased the risk of
annoyance from these sources and the need to optimise noise mitigation. The potential …

Growing demand on transportation, road, and railway networks has resulted in increased
levels of annoyance from road traffic. Optimized use of green surfaces in combination with …

A modal model formulation explains many aspects of sound propagation over complex
grooved surfaces. Insights that such a formulation offers about the intrinsic resonant …

A modal model for diffraction by a contiguous array of rectangular grooves in an acoustically-
hard plane is extended to predict the free space acoustic field from a point source above …

Sound fields above porous layers or rough acoustically hard boundaries may include
airborne surface waves. The surface wave properties depend on the effective surface …

The potential use of forests or narrow belts of trees alongside surface transport corridors to
reduce noise is often dismissed. This may be a consequence of conflicting experimental …

Regularly spaced low walls and rectangular lattices on a hard ground have been
investigated as a means for reducing noise levels from surface transport. Predictions of the …
