| Abstract | This report analyzes 34 days of near continuous noise monitor data acquired at 851 Main Avenue, Linthicum, Maryland. The site is approximately 4000 feet north northeast of the threshold of Runway l5R at Baltimore/Washington International Airport (BYI); and the measured 34 day average Day/Night Average Sound Level (Ldn) was 67.9 decibels. This value includes all noise sources; not just departure and arrival noise from BYI. An analysis of the noise data, runway use records, and maintenance ground runup logs led to the conclusion that only 65.9 decibels of this total is related to departure and arrival noise at BYI. The remaining two decibels is equally divided between nighttime maintenance engine runups and intermittent high daytime sound levels that appear at first reading to be related to the instrument calibrations. Tests were applied to determine whether or not the value of 65.9 decibels was indicative of long term average exposure. These tests used supplemental runway use data and long term noise monitor data from the BWI permanent noise monitor system to determine whether the use of Runway 15R/33L during the noise measurement period was typical of annual average conditions. The results of this analysis indicate that because of the large day-to-day Ldn variability and the small fraction of the year the noise levels were monitored, there is a four decibel range of uncertainty in the annual average value, and that 65.9 probably lies on the lower side of that range. |
