Or at least as long as it takes to get the survey finished please. That’s one reason why wind turbine noise surveys can take so long. We need to collect a lot of wind and noise data to be able to make a good assessment of the viability of your project from a noise point of view, and we can’t use data when it rains. So, based on recent evidence we can categorically advise that whatever you do don’t book the survey in the summer months!
And of course those additional site visits to calibrate equipment and make sure everything is going to plan do add to the cost. Sorry. Can’t change that. But we can promise our usual great service to help your project to completion.
