• 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.
