Abstract:

This report is the seventh in a series of seven documenting the FAA helicopter noise measurement program conducted at Dulles International Airport during the summer of 1983. The BV234/CH-47D test program involved the acquisition of detailed acoustical, position and meteorological data.

This test program was designed to address a series of objectives including:

1) acquisition of acoustical data for use in assessing heliport environment impact,

2) documentation of directivity characteristics for status operations of helicopters,

3) establishment of ground-to-ground and air-to-ground acoustical propagation relationships for helicopters, 4) determination of noise event duration influences on energy dose acoustical metrics, 5) examination of the differences between noise measured by a surface mounted microphone and a microphone mounted at a height of four feet (1.2 meters), and 6) documentation of noise levels acquired using international helicopter noise certification test procedures.
