In this work, a numerical model to treat outdoor sound propagation in the time domain is proposed. In the context of railway noise, extended acoustic sources in motion...

A new prediction method for acoustics is proposed for the mid and high frequency range: the intensity potential approach (IPA) is based on the local power balance. The...

Noise accounts for major societal matter, especially in urban and peri-urban areas where noise sources arising from road traffic are numerous and varied. Based on...

Long range sound propagation in the atmosphere is influenced by several effects: atmospheric turbulence, sound-speed gradients, ground properties (impedance, rugosity)...

Outdoor sound propagation is strongly influenced by the environment. The geometry, such as topography and the presence of obstacles, alters the sound through...

This work is dedicated to present and validate a new and generalized macroscopic nonlocal theory of sound propagation in rigid-framed porous media saturated with a...
