Experimental results of amplitude-frequency response for acoustic emission sensors are obtained by using a mechanical source of continuous noise.The amplitude-frequency characteristics of a calibrated transducer are analyzed during the registration of longitudinal, surface and Lamb waves.Experimental characteristics of different-type bandpass sensors installed on the object are discussed.
