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.
