You may enter source noise and distance for up to ten wind turbines in the worksheet below to calculate the resulting sound at a particular point. The calculator assumes that sound absorption and reflection cancel one another out, although local noise regulations may specify rules for this. You should have read the pages on Sound from Wind Turbines and Measuring and Calculating Sound Levels before using the calculator. You may learn more about the technical details of sound calculations in the Reference Manual on Acoustics.
