Abstract:A new way is proposed to eliminate the transfer matrix parameters of a rectangle anechoic elbow based on the plane wave theory.The main steps and formulae are discussed to analyze acoustical performance of a ventilation and sound insulation window using a transfer matrix method.Sound insulation of a real ventilation and sound insulation window are calculated and measured,both in good agreement.
Keywords:sound insulation window  ventilation  transfer matrix
