A. Zarembowitck, Ultrasonics internationl’91 conference and exhibition, Program and Abstra-ct book - 59 One of the most exciting results of non-destructive testing is believed by D. Gough and his collaborators in 1985 . Through his inversion of the diurnal data, his collaborator deduced the density and sound velocity at different depths within the sun. A century after Rayleigh’s Elastomeric Surface paper was published, Gough’s research showed that if necessary, the sonographer should learn more from geophysicists. Conversely, much of the information about the internal structure of the Earth obtained by the Institute of Acoustics is also worth mentioning: first of all, to prove that the Earth is like a sphere with a distinct core and that the core is solid and the core is liquid. If we understand the work of Love, Stoneley and many dedicated to geophysics scientists, we will think that the above statement is very
