ItвЂ™s not clear if the new map accurately reflects the experience of many Charlotteans under the various flight paths of departing aircraft. The results are A-weighted noise levels that represent the approximate average noise energy due to transportation noise sources over the 24 hour period at the defined receptors. вЂњWe have people who live 20 miles away who say itвЂ™s a significant impact when a plane flies over their house,вЂќ said Cagle. ThatвЂ™s the problem we have with it.вЂќД¬agle said that while some people who live within a mile or two of the end of runways have declined to sell their houses, other people from much further away feel strongly, and call Charlotte Douglas to complain.

вЂњThe FAA hasnвЂ™t changed their requirements and rules about how we determine noise impacts,вЂќ said Cagle. I was expecting B and M to behave differently but they seemed to. The Sun Is a Compass: A 4,000-Mile Journey into the Alaskan Wilds The gripping story of a biologistвЂ™s human-powered journey from the Pacific Northwest to the Arctic to rediscover her love of birds, nature, and adventure. Noise Monitoring Services is California's leading acoustic consultancy, providing noise & vibration studies, measurement and testing. The new map doesnвЂ™t change any of that, Cagle said. You can also adjust the noise frequency F. Brent Cagle, aviation director at Charlotte Douglas, said the airport completed updates to its noise map last year, a procedure that determines which properties are eligible for federal noise mitigation funding.
