We know there is less heat in the Nordic high latitudes relative to regions closer to the equator and this changes the behaviors of the atmosphere and its processes. Part of a TEKES funded project in Finland has started which intends to determine how the northern latitude weather effects the propagation of acoustics from wind turbines. By using statistical learning methods to model the relationship between the acoustic and weather parameters, a better understanding of the northern climate’s effects on the propagation will be developed. Another phase of the project involves quantifying the perceptions of the acoustics on citizens living closest to the wind park.
The project is collecting acoustic information at an aggregate rate of 102,400 samples per second using four microphones. Both acoustic and weather data will be collected for a full year’s duration. The image above is an example display of wind speed and direction observations for a single day from the project’s sodar instrument. A description of the WindSoMe project in Finnish is located here.
