Mr. Daryl Kennedy:

There are some claims in this regard, and we have read quite a bit about the health issues. Some of the claims could potentially be outlandish and we try to concentrate on the impact of noise on people's sleep. In 2012 Dr. Hanning wrote an editorial in the British Medical Journal, a journal of very high repute, and it is a peer-reviewed study. He has also showed us a peer-reviewed paper dating from September from Japan, which considers set-back distance based on sound annoyance. He can expand on that issue.
