Sound the main issue at Public Service Board hearings on Lowell wind farm
While GMP has said it will comply with any noise standard the Public Service Board applies to the project, Margolis questioned whether they would have the tools to do so if real-world noise levels turn out to be higher than expected from the modeling. Turbines can be switched to a "noise-reduced operation" (NRO) mode, but the current project design already calls for NRO mode to be used, perhaps for thousands of hours a year, to comply with the 45 decibel standard.

The Public Service Board began its third week of hearings on the Kingdom Community Wind project in Lowell with a bang. Or at least with the argument by a noise expert that wind turbines sound similar enough to banging noises like explosions, guns firing, and sonic booms that the Public Service Board ought to require the developers to ensure that their sound is quieter than it otherwise would need to be.
Leslie Blomberg, executive director of the Noise Pollution Clearinghouse in Montpelier, testified on behalf of the Lowell Mountains Group, which opposes the 63 MW, 20- or 21-turbine project that Green... [continue via Web link]
