DERMINATION OF TRUCK NOISE LEVELS FOR NEW JERSEY
The truck noise project was initiated for the purpose of more accurately predicting traffic noise levels using the Transportation Systems Center Prediction Program by regrouping highway trucks into two or more classifications. Included is the establishment of reference peak noise levels for these new classifications. Each reference level will be the average peak level determined for trucks in a particular class. Direct measurements will be made of the noise of individual trucks traveling New Jersey's highways. The major part of this interim report covers the measurement methodology developed, including field procedures and equipment, and the measurement sites selected, including criteria for selection. Data reduction and analysis are discussed briefly. Field measurements are still underway, and no experimental results are included in this report. A measurement methodology was developed which will assure that accurate A-weighted noise levels of individual trucks passing the microphone position can be obtained. Thirty-eight measurement sites were selected and the data which will be gathered at them should be representative of New Jersey's truck population. These sites also have the physical characteristics required for the accurate measurement of noise. /FHWA/
