According to the information in Addressing Wind Turbine Noise, sound levels from Pattern/Bio-Logical Capital’s proposed wind farm on the West End would be disrupting and potentially dangerous to ALL residents and visitors. Forget about sunsets at the beach!
If you don’t have time to read the entire document, some good information begins on page 8. The 3MW wind turbines proposed for Molokai and Lanai would probably emit about 105 decibels, falling to 50 db at about 1/2 mile. Lower frequencies travel further (page 15). If downwind (On Molokai the trades would make many people downwind), the noise can be heard for 3 miles or more (page 16).
At 60 db, 90% of people will have sleep interrupted most nights. At 45 db, 10% of people will be awakened most nights.
Many States have regulations on noise levels near homes. Does anyone know about Hawaii noise regs?
