Transmission Line matrix method for sound propagation modelling in forests: comparison with in-situ measurements
Résumé
The current efforts to adapt a numerical method to the
modelling of sound propagation in forests are presented in
this paper. It is relevant to professionals and researchers
in environmental acoustics and those interested in study-
ing sound propagation in complex outdoor environments
using numerical modelling techniques. The study aims
to demonstrate the applicability of the method in com-
plex media in which sound waves undergo multiple re-
flections combined with ground effect during their prop-
agation from a sound source and a receiver point. The
Transmission Line Matrix (TLM) method is used to per-
form numerical modelling of sound propagation in a 3D
forest geometry generated based on a real tree distribu-
tion case. Results are discussed qualitatively in this paper.
Their validation by comparison with in situ measurements
will be presented at the conference.
