1. Uncertainty Analysis of the Harmonoise Road
Source Emission Levels
James Trow, of Hepworth Acoustics Ltd,
and Simon Shilton, of Acustica Limited, worked together to
research the effect
of uncertainty in studying road traffic source parameters following
the publication of the Harmonoise methodologies. Their findings
point to the desirability of incorporating methods of uncertainty
analysis directly into Harmonoise calculations in order to
support the design of datasets which will provide increased
quality and reliability in source emission levels.
