Letter to Falmouth: Wind 2 turbine and noise

This important letter to the Town of Falmouth (Massachusetts) explains how the relocation of the Wind 2 turbine would result in continued noise violations. The author, Robert Rand, an acoustician experienced in turbine noise, warned that the turbine would need to be situated at least 2923 feet from the nearest neighbor in order to remain in compliance with governing noise regulations. The letter is posted below and accessible by clicking the document icon on this page. The supporting evidence is included with the document.

Re: Wind Turbine Relocation Study, Weston & Sampson Report October 12, 2018

Mr. Suso, Mr. Palmer,

This letter is respectfully submitted to the Town of Falmouth to provide a qualified professional opinion about the proposed relocation of Wind II. The original permittings for Wind I and Wind II (and NOTUS) resulted in neighbor complaints soon after start-up and were confirmed to exceed Falmouth’s 40-dBA noise limit (turbines sited too close). Weston & Sampson's relocation recommendation for Wind II appears to be inconsistent with the Town 40 dBA noise limit and the 2017 Barnstable Superior Court Decision. 

1. The distance to meet 40 dBA for Wind II, a Vestas V82 with sound power level of 110 dBA, is approximately 891 meters or 2923 feet. This is greater than the setback distances
provided by the proposed new location. The proposed new location is still too close.

2. At 2147 and 2244 feet listed in the subject report, the expected sound level is 43 dBA. 

3. Use of the proposed new location appears certain to result in the relocated wind turbine's maximum noise levels exceeding the Falmouth noise limit of 40 dBA.

4. Use of the proposed new location appears certain to result in the relocated wind turbine's maximum noise levels exceeding established background sound levels of 27-28 dBA by over 10 dB, breaching State 10-dB noise limits.

Supporting detail is provided below. Please contact me if you have any questions.

Respectfully Submitted,
