Summary:

Repetitive J-366 pass-by tests were run on a number of trucks to determine the effect of atmospheric conditions on the measured pass-by noise level. Of the atmospheric conditions observed (temperature, wind, humidity, air density and sunshine), only ambient temperature had a significant effect on measured pass-by noise. Measured pass-by noise level increased approximately 1 dB(A) for each 13 °C drop in temperature. Data indicates that applying a generic correction factor based on engine type is more accurate than ignoring the effect of temperature
