1 meter/second = 2.24 miles per hour=3.6kph

2 Output range is quoted to cover typical average wind speeds (annual). Lighter wind

sites with typical 4.5m/s will produce lower end of range. Higher wind speed sites e.g.

6.5m/s average will produce upper end of range.

3 All readings taken with an ATP SL-25 dBA meter at the base of the tower at a height of 1.5m.

* A car passing 20m away @ approx 40 mph is 70-80dBA
