Why_dB28A29_doesn_t_work_for_wind_farm_noise.gif
Why dB(A) doesn't work for wind farm noiseWhen turbines are shut down, the unweighted, C-weighted, and LAeq(LF) levels drop correspondingly, whereas A-weighted level does not.

measured-louder-than-predicted.png
Measured wind turbine noise louder than predictedAt 10 different facilities, acoustical engineers Robert Rand and Stephen Ambrose measured wind turbine noise to be 3-12 dB (average 4.5-9 dB) louder than had been predicted.

Perception of and annoyance by noise from wind turbinesFrom Pedersen E, van den Berg F, Bakker R, Bouma J. Response to noise from modern wind farms in The Netherlands. Journal of the Acoustic Society of America 2009;126(2):634–43.
wind-sun-demand.png
Wind generation vs. sunlight and demandWind-power generation (blue), insolation (gold), and power demand (red) time series data show wind energy's poor correlation with demand. Thirty days of data collected in April 2010 from Bonneville Power Administration are superimposed and normalized to their maximum values. Average values are in color-highlighted black lines.
