“…In the case of numerical techniques, the boundary element method and the "nite element method (FEM) are the most interesting ones (see references [17,18]). One of their major advantages is the possibility to analyze problems with arbitrary geometry and general boundary conditions, but at the cost of long computation times if su$cient accuracy is desired at high frequencies, due to the large number of elements required.…”

“…This approach relies on the Integral Equation theory which was developed in the 1960s and has been since extensively used. 12 Its main advantage is that it allows any kind of shape and absorption of the surfaces to be taken into account for in a homogeneous atmosphere.…”

A number of reference numerical models can be used to perform outdoor sound propagation prediction in a complex environment. Most of time, either they consume little computational time by not taking all phenomena into account at the same time, or they are more complete but their calculation times are prohibitive. This paper presents some principles which can be used in reference numerical models to reduce calculation times in predicting long-range outdoor sound propagation under complex environments. Limits, assumptions and approximations used to predict outdoor sound propagation are discussed here in terms of their impact on accuracy for typical road traffic configurations as a function of frequency, geometry of the site and atmospheric conditions.

Abstract:In this study, a coupled model is developed to address the dynamic response of an offshore pile to linear water waves. In the coupled model, the pile and the seabed are treated as a saturated poro-elastic medium described by Biot's dynamic theory, while the seawater is considered as a conventional acoustic medium. To establish the coupled model, boundary element formulations for saturated porous media are derived for the pile and the seabed, respectively, and the acoustic boundary element formulation is constructed for the seawater. The coupled boundary element model is obtained using these three boundary element formulations as well as the continuity conditions along the interfaces between the pile, the seabed and the seawater. In the model, linear water waves are considered as an external load and its load is evaluated via the wave function expansion method. Numerical results shows that increment of the modulus ratio between the pile and the seabed can reduce the horizontal displacement of the pile and the pore pressure of the seabed around the pile. Also, the maximum pore pressure of the seabed usually occurs at the upper part of the seabed around the pile.
