Wind Deflectors let you enjoy cool, fresh air without all the noise and swirling winds, so you don't have to be so quick to crank up the air conditioner. Plus, deflectors improve your vehicle's open-window aerodynamics, cutting down on drag for a more efficient ride.
quency and that the low-frequency noise would cause annoyance for the neighbors. The noise emis-. sion from 48 wind turbines with nominal electric power up to 3.6 MW is analyzed and discussed. The relative amount of low-frequency noise is higher for large turbines (2.3â3.6 MW) than for. small turbines ( 2 MW), and the difference is statistically signiï¬cant. The difference can also be.
