If models low-ball noise, will ears cooperate?
Acoustician Stephen Ambrose has released a one-page illustration (with the two graphs shown here) of the difference between modeled noise and the experience of measured noise as described in an RSG report from 2008. Modeling the current class of industrial wind turbines turns out to be a poor predictor of noise, either as recorded by instruments or as heard by the humans who come into contact with it.
Ambrose’s reminder comes at a time when the Wind and Noise Turbine Advisory Group (WNTAG) is about to have it’s “final” meeting, which will feature the “final report” the DEP plans to issue. According to Bethany A. Card, Deputy Commissioner for Policy and Planning of the MassDEP, in an email on March, 14, 2016:
The March 18th meeting is to provide an overview of the final report. In addition, MassDEP will also present ideas for possible revised noise policies and regulations. We will accept comments on that presentation and the ideas until early April and any on-going work related to possible regulation changes will provide additional opportunity for stakeholder and public involvement and comment.
