Superior sites logged 71 and 92 hours above aircraft-noise threshold in August
The town’s report modeled lower totals if subsequent touch-and-go training operations occurred elsewhere; the estimates are not measured reductions.

Aircraft noise was at least 5 decibels above ambient sound for 71 hours at Superior’s Water Bladder monitoring site and 92 hours at Pirate Park in August, the town’s monthly monitoring report found. The report defines that margin as “clearly noticeable.”
The report recorded an average of 171 minutes per day above the threshold at Water Bladder and 178 minutes at Pirate Park. Water Bladder had no noise data from Aug. 1 through 6 because of equipment malfunction.
The report also modeled a scenario in which subsequent touch-and-go training operations—when a pilot lands and takes off again—were conducted elsewhere. It estimated that time above the threshold would fall by 35%, to about 46 hours at Water Bladder, and by 26%, to about 68 hours at Pirate Park. The model assumes noise from those subsequent operations would be at ambient levels while retaining noise from the initial takeoff and landing. These are modeled estimates, not measured reductions.
