COLCHESTER (AP) - The Vermont Public Service Board is considering whether the standards it sets for the noise generated by wind turbines and other energy projects are stringent enough.

Geoff Commons is the public advocate for the Department of Public Service, which represents rate payers before the board. He says that until now, projects have been held to a 45 decibel level consistent with the World Health Organization.

But he tells Vermont Public Radio further study is warranted because neighbors of large-scale wind projects continue to complain about the sound produced by the whirring blades.

Commons says the science of health effects from wind turbine noise has not been settled and the board is trying to get the best information it can.
