How does the Dual Pane Acoustic Glass in the Audi A7 improve soundproofing?

I've heard that the Audi A7 has soundproofing technology, but I'm wondering exactly how it works. Can you explain how the Dual Pane Acoustic Glass contributes to a quieter ride?

The Dual Pane Acoustic Glass in the Audi A7 consists of two layers of glass with a layer of special acoustic film in between. This helps to reduce outside noise and vibrations, creating a more peaceful driving experience.

When purchasing an Audi A7, you have the option of upgrading to Triple Pane Acoustic Glass for even further soundproofing. But even with the standard Dual Pane Glass, you'll notice a significant reduction in road and wind noise.
