Abstract : An electronic test method for determining frequency response characteristics of ultrasonic transducers is described. The method involves an actual transmission and reception of ultrasonic signals and yields the loop response curve of a transducer. In examining the frequency response of a number of commercially made ceramic transducers, large variations are found. It is concluded that for a correct correlation of ultrasonic test results, the complete transducer response curve should be known and included in the manufacturer's specifications. (Author)
