Notes: 1 meter/second = 2.24 miles per hour = 3.6 kph, 1 kg = 2.20 lbs., 1 meter = 39.37 inches (3.2808 feet), Output range is quoted to cover typical
average annual wind speeds, lighter wind sites with typical 4.5m/s will produce lower end of range, higher wind speed sites (6.5 m/s average) will produce upper end of range, all readings
taken with an ATP SL-25 dBA meter, car passing 20m away @ approx 40mph is 70-80 dBa
