- Аннотация: In this paper, we describe a diagnostic method based on “acoustic weighing” of sheet materials.The defect mass or mass deficit determines the frequency shift of the oscillating membrane. The measuring device of Academician N.N. Andreev invented in 1925 and based on the effect of “rattling” due to the “bouncing” of a small weight lying on a telephone membrane is described. The harmonics that appear at sufficiently large oscillation amplitudes are calculated. It is shown that harmonics can also appear during the operation of modern high-precision instruments, for example, tunneling and atomic force microscopes
