Abstract:
NOISECHECK is a measurement program used 1 when an engineer is uncertain about a Sound Exposure Level SEL resulting from a particular type of operation or 2 to check noise contours determined by NOISEMAP - an Air Force computer program. The file of aircraft noise data used by NOISEMAP is called NOISEFILE. The NOISECHECK measurement program uses portable noise monitors that measure Day-Night Sound Levels DNLs over one or more days as well as individual Sound Exposure Levels SELs. The measured DNLs are then compared with the DNLs calculated by NOISEMAP, or they contribute SEL data for comparison with NOISEFILE. This report delineates the field test data acquisition and analysis procedures used to conduct NOISECHECK type measurement studies. A companion report, AMRL-TR-78-125, Development of NOISECHECK Technology for Measuring Aircraft Noise Exposure, describes the instrumentation development and subsequent field test conducted at Barksdale AFB as part of this research effort.
