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 …

The sound environment in urban areas is complex, as caused by many sources of sound
and influenced by a variety of acoustic propagation effects. In order to combat noise and …

The urban fabric largely consists of acoustically rigid materials. This not only affects sound
pressure levels in streets, but also how sound propagates towards the back side of a …

An open source implementation of the Fourier pseudospectral time-domain (PSTD) method
for computing the propagation of sound is presented, which is geared towards applications …

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 …

A surface homogenization method for acoustic waves over thin microstructured surfaces in
the presence of a fluid in a potential flow is presented. Sound hard surfaces are considered …

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

Propagation of an airborne acoustic pulse from a point source above an array of regularly
spaced rigid cylinders on a rigid plane has been investigated using a two-dimensional …

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 …
