【Abstract】 This paper presents the experimental technique for measuring the vibrational cha-racteristics of an electroacoustic transducer on the basis of the time-average holographicinterferometry principle. The relation between holographic vibrating modes and the acous-tic amplitude of the transducer is also described. Finally, a new method of calculating theacoustic radiation power of the transducer with the dada from measurement by time-avera-ge holographic interferometry instead of measurement in anechoie chamber is introduced.更多还原
