Abstract:

The U.S. Department of Transportation, Federal Aviation Administration, (U.S.DOT/FAA),

along with the U.S. DOT, Research and Special Programs Administration, Volpe National

Transportation Systems Center (RSPA/Volpe Center) conducted a helicopter noise

measurement flight test in Champaign, Illinois, during the period July 22 through 26,

1991. The primary objective of the study was to obtain the field data necessary to

examine the feasibility of a simplified helicopter-noise-certification procedure

(screening test). Acoustic data were measured by and stored on a hand-held sound level

meter (on-line processing) and recorded on digital tape for later off-line

processing. A comparison of the measured on-line acoustic data with the acoustic data

processed off-line provided the foundation necessary to evaluate the feasibility of

the proposed screening test. In addition to acoustic measurements, meteorological

data and helicopter tracking and performance data were also obtained.
