Submission to Health Canada Wind Turbine Noise and Health Study, 2012

I would like to bring to your attention the very important issue of land typography and its needed attention in your study design and methodology.

At present, there is a project proposed for the Nor'Wester Mountains in Thunder Bay, ON which is to be on a 600 foot escarpment facing a rock-face with homes in the valley below. I understand the computer models that Wind companies use are all based on flat land and do not consider land typography. I understand the computer models also underestimate noise levels. This is of great concern to our community as there is a school and over 750 homes in the valley below.

Please consider including land typography as it pertains to wind turbine noise travel. There is very little research in this area.

In addition, please consider the following variables:

Thanks for undertaking such an important study area and I wish you well in your research design efforts. As a qualified Pychometrist, I understand the complexities involved and how important it is to properly design a study.
