Mathematical model of engine as sound source and of its exhaust as acoustic wave guide; spectrum of exhaust sound of engine with exhaust turbine superchargers can be computed with aid of expression based on choked nozzle model of exhaust turbine, exhaust pulse function simplified into trapezoidal curve with corresponding Fourier analysis and linear acoustical theory about sound transmission in thin long waveguides and filters, using scale models and neglecting direct gas flow.
