There have been significant and widespread community complaints. Despite compliance testing by the operators and assessment of nuisance by the local authority, significant complaints continue without any resolution. A lack of clear guidance on how to assess AM is the reasoning of the local authority for failure to act and the operator's compliance testing has shown that the wind farm can, in a reduced operational mode, meet its limits. In 2013 MAS Environmental established a permanent monitoring station to record and publish data online, located 600m from the nearest turbine. This allows correlation of impact upon the community and establishes a library of wind farm noise data. This paper reviews the long lasting impacts of the wind farm and using data from the community monitoring station investigates how a 'compliant' wind farm continues to cause significant disturbance. The averaging processes used by many when assessing compliance with ETSU-R-97 are examined in relation to specific complaints and the new UK Institute of Acoustics and WSP / Parsons Brinckerhoff methodology for quantifying and assessing AM is tested. Using real world data from a site where there are continuing complaints, this paper assess whether current methodologies for assessing noise impact are fit for purpose.", }
