The report provides information regarding the environmental noise levels at sixteen locations in the City of Mountain View, Georgia, adjacent to Hartsfield International Airport in Atlanta. Continuous twenty-four hour monitoring of environmental noise levels was conducted at the selected sites for periods of time ranging from two days to three weeks. For each of the locations examined, the minimum information obtained on an hourly basis was--the hourly equivalent A-weighted sound level Leq(1), the maximum A-weighted sound level for the period, L50, the A-weighted sound level exceeded 50 percent of the time, and L90, the A-weighted sound level exceeded 90 percent of the time. Results of the data analysis showed average day-night sound levels, Ldn, higher than 85 dbA at two locations. In addition, the measured Ldn exceeded 80 dbA on several occasions at four additional sites. Typically, Ldn exceeded 75 dbA at all other locations over a measuring area of approximately 1.5 square miles.
