B-1 Appendix B: T.F. Green Airport (PVD) Taxi Noise Measurements B.1 . T . F . Green State Ai rpor t Tax i Noise Measurement Setup Aircraft taxiway noise was measured at T. F. Green State Airport (PVD) on March 24, 2008. In addition to sound level meters, a video system was deployed in order to obtain aircraft speed and positional information. The accessible measurement location was selected based on the prevailing weather conditions and active runway configuration. The measurement location was adjacent to taxiway T adjacent to runway 5 (Figure B-1). The measurement site was situated approximately 234.81 feet (71.57 meters) from the point of closest approach to an operation (Figure B-2). The taxiway centerline can be seen in figure B-3 highlighted in bold yellow. One Larson Davis 824 sound level meter (SLM) was placed at position Tango1 shown in figures B-2 and B-3. The SLM was placed 1.5 m (4.9 ft) above the ground. The SLM was programmed to collect A-weighted and one-third octave band 1-second time histories. Figure B-1. T. F. Green State Airport

TRB’s Airport Cooperative Research Program (ACRP) Web-Only Document 9: Enhanced Modeling of Aircraft Taxiway Noise, Volume 1: Scoping explores ways to model airport noise from aircraft taxi operations and examines a plan for implementation of a taxi noise prediction capability into the Federal Aviation Administration's integrated noise model in the short term and into its aviation environmental design tool in the longer term.

ACRP Web-Only Document 9: Enhanced Modeling of Aircraft Taxiway Noise, Volume 2: Aircraft Taxi Noise Database and Development Process documents the procedures developed and employed in the creation of a taxi noise database for the U.S. Federal Aviation Administration’s Integrated Noise Model and Aviation Environmental Design Tool (AEDT). The AEDT is currently under development.
