Citizens have tried traps, poisons, high - frequency noise emitters, and all sorts of devices to fight the problem, but one method seems to be working better than the rest, so long as you can get it to stick around.

The problem of differentiating the signal of intensity from the noise of frequency remains, and I for one can not think of a research question that could draw from this data an answer to the «Is AGW causing increases in hurricane losses?»

This industry has been well aware of the problems directly caused by wind turbine noise since 1987, when Dr Neil Kelley's research [12] establishing direct causation of annoyance symptoms from infrasound and low frequency noise was presented at the American Wind Energy Association conference.
