Ford is using Noise Vision technology and virtual reality to create the best sounding vehicles ever
Just last week Ford invited us to Dearborn so that we could preview what the American automaker has in store for the upcoming North American International Auto Show, although we can’t extrapolate on the Detroit cars for a few more days, we can tell you about what the blue oval is doing to ensure that their future products sound better then ever. Whether it be the elimination of undesirable noise vibration and harshness or the amplification of Mustang GT’s V8 rumble or the turbochargers on Taurus SHO’s EcoBoost V6, Ford is going to great lengths to ensure that new car buyers hear everything that they are supposed to, and nothing else.
Our tour started out inside a clean room where Ford’s NVH engineers demonstrated their latest toy, Noise Vision. This state of the art technology is currently being used exclusively by the American automaker, with a little help from two very import sources, Pythagorus and Einstein. The first is an all new instrument that is made up of 31 highly sensitive microphones and 12 different cameras spaced out along the outside of the $200,000 black sphere that create a full 360 degree image of the area being tested. The unit was affectionally named after the 6th century BC Greek philosopher because it is the mathematicians theorem that is used to carry out the calculations being computed by the new Noise Vision system before being projected onto a two dimensional display that can easily be interpreted by Ford’s sound team. Einstein is a traditional Aachen Head, a specially developed sound receiver with microphones mounted inside of a mannequin’s cranium and recreates the human ear canal to ensure the most authentic listening experience possible. Continued with press release and videos after the jump.
Ford’s NVH engineers use their newfound Noise Vision technology to identify every source of unwanted noise and then catalog their audi waveforms into an extensive database for future cross referencing with newer vehicles. While this setup sounds like the perfect tool to fix that annoying rattle hiding behind your passenger side door panel, don’t expect to see one in your local dealer’s service shop anytime soon. Due to the unit’s extreme cost and expertise required to properly use the system, the setup is a bit too pricy for personal use. So it looks like Pythagorus and Einstein won’t be making any travel arrangements out of Dearborn any time in the near future.
The next stop on our tour took us to Ford’s new Virtual Vehicle Sound Simulator, think of it as the most elaborate Gran Turismo setup you have ever seen this side of a Formula One simulator. The virtual test road allows Ford’s engineering team to look at how everything from road surfaces to exhaust systems and even motor mounts effect what you hear inside the cabin. The largest benefit of the virtual test bed is that engineers can switch back and forth from one vehicle to the next instantaneously without any time to forget what they were just listening to, this allows them to tune the sound of every single new vehicle so that they are all distinctly Ford.
Once the blue oval engineers find the right note in the virtual world, they must then figure out a way to deliver it in real life. This is where the world of those black plastic boxes you find connected to the intake tract under the hood that they like to call Helmholtz Resonators. Aside from designing these units and mufflers to deliver anywhere from a hush to a roar depending on what they feel the customer is after, Ford is also using a few unconventional components to add a bit more attitude into their performance vehicles. Two very interesting pieces being the SHO’s sound generator that amplifies the turbos spooling up sound while Mustang GTs have a sound pipe that directly connects the V8 to the vehicle’s cabin and makes a big difference when you stand on the throttle. So no matter whether you are looking for a relaxed luxury ride or a roaring sports car, you can rest assured that Ford is doing everything they can to make that happen.
