Abstract
An acoustic glazing intended for land transportation vehicles and including first and second glass sheets separated by an interlayer region, wherein the acoustic transmission loss differs at most by 5 dB from a figure increasing of 9 dB per octave from 800 to 2000 Hz and of 3 dB per octave above that. As examples, double glazings or laminated glazings are presented featuring an interlayer with a pronounced damping. The acoustic glazing will then operate to effectively eliminate aerodynamic noises in moving vehicles.
