Plug the sound tube, to prevent sound from flowing? You guys seem to know, what are we talking about?
The Lexus IS200t F-Sport has something similar, called an "Active Sound Generator" with an ASC button on the dash to turn it off.Ford has a tube on their intake that runs through the firewall behind the dash somewhere that lets engine sound into the cabin. Dumbest thing ever.
So when I hear my challenger, I want to be sure it is my Challenger so I always roll the windows down when traveling between 2 concrete barriers, on a bridge or in a tunnel or under an over pass, and "Nail it" just to make sure!When the engine is so muted (and cabin insulation) - they resort to having a resonance tube connected to the firewall.
Even more lame is when they pipe "engine" sounds through the stereo system:
.BMW's Active Sound Design tech replicates engine noise inside the M5's cabin using the car stereo's speakers. What ever happened to just rolling down the windows?www.cnet.com
