Essentially we have to measure wind speed and direction and tie that up neatly with the existing background noise at the nearest property to the place you want to put your turbine.
To get a good idea of wind speed and direction we install a tall mast with an anemometer on top. We would usually install this at the proposed location of your turbine. We have to secure this tall piece of kit with guy ropes to make sure it stays upright in the wind so it’s fair to say we need a good size piece of ground to get the thing safely doing its job.
For noise, we would install equipment at the nearest sensitive off site receiver – usually a neighbouring residential dwelling. We need to leave both pieces of equipment out for usually up to two weeks, that’s to make sure we have a large enough sample of data to show the Local Authority that ‘s representative of typical conditions. There are occasions when we’d need to leave the equipment out longer. Rain stops play, and obviously a little bit of wind is useful!
