A noise study was conducted at Washington Dulles International Airport to further investigate the noise and vibration impact of thrust reversers and start of takeoff roll on communities near runways. Two different houses located on the airport property were instrumented with outdoor and indoor microphones and accelerometers mounted inside on walls, windows and floor. This presentation will discuss both the experimental design and data obtained from the two different structures. Correlations between plane types, outdoor signatures and acceleration levels are considered. The outdoor signatures and acceleration levels are used to investigate the conditions under which rattle of a loosely coupled window is observed. Additionally, the design of a subsequent subjective study to examine the effects of rattle on human perception will be discussed. The combination of the objective measurements with the results of the subjective study is intended to give a better understanding of community impact due to airport noise.
