The influence of track parameters on the sound radiation has so far mainly been studied for ballasted tracks. The increasing usage of slab tracks in new railway lines worldwide makes a review of these parameters relevant. In this paper, the structural vibrations of rail and slab are evaluated based on two waveguide finite element models that are coupled in a finite number of positions. This discretely supported rail is compared to a rail on a continuous support. The sound radiation from rail and slab is evaluated based on a wavenumber boundary element method. The slab and rail contributions are evaluated separately. It is found that comparable to ballasted tracks, the rail pad stiffness has a large influence on the radiated sound power. For a continuously supported rail, the total sound power is reduced and the rail pad stiffness is less influential.
