TRUCK NOISE-II, INTERIOR AND EXTERIOR A-WEIGHTED SOUND LEVELS OF TYPICAL HIGHWAY TRUCKS

A FIELD MEASUREMENT AND ANALYSIS EFFORT WAS UNDERTAKEN BY THE OFFICE OF NOISE ABATEMENT TO ASCERTAIN INTERIOR SOUND LEVELS AND SIMPLIFIED TEST PROCEDURES. DUE TO INTEREST IN COMMUNITY NOISE ON THE PARTS OF THE TRUCKERS AND THE DEPARTMENT OF TRANSPORTATION, THE EXTERIOR NOISE LEVELS WERE MEASURED AS WELL AS THE INTERIOR NOISE LEVELS OF THE TEST TRUCKS. INTERIOR AND EXTERIOR NOISE LEVEL DATA ARE PRESENTED FOR A VARIETY OF TRUCK OPERATING PROCEDURES WHICH INCLUDE: STATIONARY LOW IDLE; STATIONARY ENGINE ACCELERATION; STATIONARY HIGH IDLE (GOVERNED RPM); SAE J366A ACCELERATION, SAE J366A DECELERATION; AND SAE J366A ENGINE BRAKE DECELERATION. SAMPLE MEASUREMENTS OF TYPICAL OVER-THE ROAD DRIVER SOUND LEVEL EXPOSURE ARE ALSO REPORTED. AN ANALYSIS OF THE SIGNIFICANCE OF THE VARIOUS TESTS AND A RECOMMENDED ENFORCEMENT PROCEDURE FOR INTERIOR NOISE LEVEL IS REPORTED. A METHODOLOGY TO RELATE THE SIMPLIFIED PROCEDURE TO DRIVER EXPOSURE AND THE HEARING CONSERVATION CRITERION OF THE OCCUPATIONAL SAFETY AND HEALTH ACT IS PROPOSED. /AUTHOR/
