This article discusses a coupled finite and boundary element method for an interface problem related to the acoustic wave equation. It examines the well-posedness, a priori and a posteriori error estimates for a symmetric space-time Galerkin discretization related to energy. Numerical experiments in three dimensions demonstrate the method's performance in model problems.
