  • 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.
