Wind turbine noise propagation below 100 Hz
The measurement of sound at very low frequencies, below 100 Hz, is difficult and requires the use of special instruments. In the Wind Turbine Noise & Health Study conducted by Health Canada, microbarometers were used because they are capable of measuring frequencies between 0.1 Hz and 100 Hz. Microbarometers were installed at distances of 125 m, 2.5 km, 5 km and 10 km from the nearest wind turbine in […] wind turbines. The noise levels from a wind turbine can . . . Complete article »

Analysis, modeling, and prediction of infrasound and low frequency noise from wind turbine installations
MG Acoustics has carried out the analysis, modeling, and prediction of infrasound and low frequency noise from wind turbines at two different sites, as part of the Health Canada study. This work has been divided into two parts, Phase 1 and Phase 2, associated with a Prince Edward Island site and a Southern Ontario site, respectively. There are several overall objectives: investigate the use of Harmonoise/Nord2000 weather classes with Environment Canada weather data to predict sound speed profiles investigate methods . . .
