Wind turbine noise [PDF]

open access: yesBMJ, 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 ...

Clarification of influences of inflow conditions on wake of horizontal axis wind turbine

open access: yesNihon Kikai Gakkai ronbunshu, 2015
In recent years, wind turbines are introduced in wind farms in which some wind turbines are concentrated. When wind turbines are built in contiguity with each other in wind farms, the flow passing through a wind turbine, which is called wake, may flow ...
