All machinery makes noise of some sort - this is unavoidable, but it is surprising how little noise actually comes from the turbines. Both the Evance R9000 and the Gaia have been designed to minimise noise pollution, and in fact the noise they generate is sometimes ‘blocked’ out by road noise or even the wind in the trees.
Dorrell Renewables can provide detailed documentation and information on noise levels and provide evidence in the case of planning applications.
