Wind turbine noise [PDF]

BMJ, 2012
Seems to affect health adversely and an independent review of evidence is needed The evidence for adequate sleep as a prerequisite for human health, particularly child health, is overwhelming. Governments have recently paid much attention to the effects of environmental noise on sleep duration and quality, and to how to reduce such noise.1 However ...
