文摘The acoustic impedance caused by sound radiation at the terminals of the aperture on cylindrical surface is analyzed based upon rigorous sound theory. In low frequency range, the approximate solution of the specific acoustic resistance is derived. Special treatments are introduced in order to simplify the solution of the specific acoustic reactance. It is verified that the specific acoustic reactance of such an aperture is equal to that of a similar aperture on the infinitely large plane when the small quantities of high order are neglected.
