Abstract
We investigate the influence of waveguides used in acoustic emission tests of materials in corrosive environments on changes in the parameters of acoustic emission (AE) signals. A method of boundary interpolation is suggested for determining the natural frequencies of the waveguides. This method enables one to perform calculations for cylindrical waveguides of various lengths and diameters. We present analytic relations used to select a waveguide with the required geometric parameters in agreement with the resonance bandwidth of an AE transducer. This selection reduces the losses of AE signals in passing through the waveguide. Experimental investigations of the attenuation of AE signals in the waveguide are also carried out.
