Method for measuring vehicle noise source heights and subsource spectra
R Coulson - Transportation research record, 1996 - journals.sagepub.com
The US Department of Transportation in cooperation with FHWA and several state
transportation agencies is collecting a highway noise database for the development of noise-
level regression equations. These data and equations will provide the foundation for the
new traffic noise software, TNS. In addition to collecting reference energy mean emission
level data, this test plan also requires an extensive database of source heights and
subsource spectra covering all vehicle classes and possible roadway parameters. A …

[HTML][HTML] Vehicle noise source heights & sub-source spectra
RK Coulson - 1996 - rosap.ntl.bts.gov
This report describes a turn-key system that was developed and implemented to collect the
vehicle source height database for incorporation into the new Traffic Noise Model (TNM). A
total of 2500 individual vehicle pass-bys were measured with this system at 16 different sites
around Florida and these data are presented in the form of averaged curves for each vehicle
type. The dependence of source height on speed, pavement type, road grade and
acceleration state is also shown for 10 different types of vehicles. The effect of these …
