Project description

Noise issues are currently hindering deployment of wind turbines, and their low-frequent emissions are suspected to be both annoying and harmful for man. This project aims at developing a time-domain sound generation and propagation model, starting from highly-detailed fluid dynamics calculations. The mechanisms of low-frequent sound and the way they are influenced by atmospheric conditions will be elucidated.
