摘要:
A pulsing technique for measuring the blocked impedance of an electroacoustic underwater sound transducer is described. The method permits measuring the blocked impedance under free‐field acoustic loading conditions without resorting to clamping the transducer or to the usual interpolation method. Both theory and measurements are discussed. A means of readily identifying the natural resonance frequency from either an impedance or an admittance plot is also presented.
