Well you do have one of the rare windshields for Toyota. The only cars that have the "Acoustic Windshield" is the Avalon Limited (US only) and the 2009 Corolla.

Otherwise, you'll have to move up to a Lexus to get an acoustic windshield so Toyota has put some expensive stuff in the TCH all in the name of quiet.
