摘要
The study of temporal acoustic problems, linear or not, can be carried out by solving Navier-Stokes equations. The finite volume method is chosen in which the compressibility is introduced by the law of behaviour. In that case, constant isentropy is taken into account . After a short description of the basic equations, a 1D example shows how is used the boundary condition of radiation at infinity for the plane wave. Added to the calculation process a feedback loop has to control a secondary acoustic source for active noise cancellation.
