Abstract
The suitable prediction model for outdoor sound fields depends on
the situation and the application. Computationally intensive
methods such as Parabolic Equation methods, FFP methods and
Boundary Element Methods all have advantages in certain
situations. These approaches are accurate and predict not only
sound pressure levels but also phase information. Such methods
are, however, not always able to predict the sound field for more
complicated scenarios involving terrain features, atmospheric wind
and temperature gradients and turbulence. Another class of methods
is based upon approximate theory - such methods are inherently
less accurate but generally faster in computation and may also
provide results for complicated scenarios. The accuracy of
different approaches in realistic situations is discussed based
upon measured and simulated data.
