Abstract
During the implementation process of the CNOSSOS-EU, many
questions have been arisen. There are inconsistencies in
the guidance, but the most of the questions are related
to the acquisition of the initial values and their
validity. We evaluated the sensitivities of the noise
propagation part and the road noise sound power levels to
the changes of some initial values within their validated
ranges. The evaluated parameters were the probability of
occurrence of downward-refraction conditions and the
coefficients for the road surface and propulsion noise.
Measured weather values were calculated using three
approaches and compared to each other and to the default
values. The results shows that the use of the default
weather values increase the immission levels and thus the
number of exposed people. The default rolling and
propulsion noise factors of the CNOSSOS-EU method are not
usable in northern conditions and the national factors
should be exploited.
