Self and Mutual Acoustic Radiation Impedances for Pistons in a Plane Infinite Rigid Baffle

摘要

Formulas to calculate the self-impedance and mutual-impedance coefficients of acoustic radiation from disks in an infinite rigid baffle are discussed. A Fortran IV computer program which evaluates these expressions is listed, and two tables of numerical values are printed. The first table lists both the self-impedance and the mutual-impedance coefficients as a function of ka and kd, where kd = nka, for n = 2, 3, 4, ..., 151, and where ka = 0.02 (0.02) 0.10, 0.15 (0.05) 1.00, 1.20 (0.20) 3.00. The second table lists only the self impedance for ka = 2.50 (0.50) 77.0. (Author)
