| description | The invention relates to a method for selecting a viscoelastic plastic interlayer including two outer layers and a central layer that can be incorporated between two glass sheets of a glazing unit, the method includes providing first and second components that constitute respectively the central layer and the outer layers, measuring the shear modulus G′ of the first and second components, selecting the material of the second component only if G′≧3×107 Pa at 20° C. and between 100 Hz and 240 Hz, and setting the thickness h of the first component so that h is between 0.31 mm and 1.20 mm and so that g=G′/h is between 5.58×108 Pa/m and 2.37×109 Pa/m at 20° C. and between 100 Hz and 240 Hz. |
