TRUCK-NOISE MEASUREMENT
THIS DISCUSSION DEALS ENTIRELY WITH THE PROBLEMS OF MEASUREMENT, FIRST WITH SPECIFIC EQUIPMENT AND TECHNIQUES FOR MEASURING AND RECORDING AND SECONDLY WITH EQUIPMENT AND TECHNIQUES FOR EVALUATING THE MEASUREMENTS. INSTRUMENTATION IS DESCRIBED IN WHICH NOISE MEASUREMENTS MAY BE MADE EITHER BY INTEGRATING (TOTAL-NOISE) DEVICES OR BY INSTRUMENTS WHICH DIVIDE THE NOISE INTO FREQUENCY BANDS AND GIVE A READING FOR EACH BAND. FIELD AND LABORATORY TESTS HAVE BEEN MADE ON NOISES PRODUCED BY LARGE TRUCKS EQUIPPED WITH DIFFERENT MUFFLERS. ANALYSES ARE MADE OF THE TESTS TO DETERMINE THE CORRELATION BETWEEN MEASUREMENTS ON 16 DIFFERENT MUFFLERS AND JURY EVALUATIONS OF THE NOISE. THE RESULTS INDICATE THAT THE AMERICAN STANDARDS ASSOCIATION SOUND-LEVEL METER CAN BE USED AS A SATISFACTORY INSTRUMENT TO INDICATE THE ANNOYANCE VALUE OF TRUCK NOISE, IF USED ON THE PROPER SCALE AND SET UP IN THE PROPER MANNER. /AUTHOR/
