Editor:

As I read letters about the noise related to wind turbines, one question comes to mind that I need readers’ input.

I have very limited experience with wind turbine noise directly, but am familiar with the noise of the ocean surf.

Question: How does the noise of wind turbines compare with the noise generated by the surf?

For a comparison of these two noise effects please base it on the following points:

a. The energy spectrum of the noise (how the power of the noise varies with frequency).

b. The temporal (time) distribution of the noise.

c. The duration and consistency of the noise.

Please cite specific, peer-reviewed, sources for your information.

Thank you for helping me find some detailed data on this complex subject.
