Use of a laminated glazing to dampen solid-transmitted vibrations in a vehicle

An acoustic protection screen for a vehicle comprises a laminated screen consisting of at least one glass layer and an inserted film having a loss factor, tan delta , greater than 0.6 and a shear modulus G' less than 2 x 10 N/cm , in a temperature range of 10-60 degrees C and a frequency range...

More Information
Summary:An acoustic protection screen for a vehicle comprises a laminated screen consisting of at least one glass layer and an inserted film having a loss factor, tan delta , greater than 0.6 and a shear modulus G' less than 2 x 10 N/cm , in a temperature range of 10-60 degrees C and a frequency range of 50-10000 Hz. Also claimed, is the insertion film capable of giving acoustic insulation and the laminated screen obtained in this way.
