Noise cancelling technology has been around for a while and is employed by nearly every automaker. Whether it's dense foam insulation, thick carpets, technological innovations, or recommending a certain tire compound, there are many ways automakers work to keep road and engine noise from permeating the cabin.

Hyundai is taking those traditional methods of sound-blocking even further with the world's first Road Noise Active Noise Control (RANC) system, which the company says "dramatically reduces" cabin noise.

RANC is the next step in active noise control technology and works by emitting sound waves that have been inverted to incoming noise. Think of it like two magnets repelling each other.

Previously, active noise control technology only allowed predicted noises to be able to be muted.

"RANC is a remarkable technology which takes existing noise, vibration, and harshness (NVH) technology to the next level," said Gangdeok Lee, a Research Fellow of NVH Research Lab, "We will continue to take the leading position of NVH highest level of quietness to customers."

The new RANC technology, which took six years to develop, analyzes road noise in real time, using an acceleration sensor, and calculates the vibration from the road to the car. A computer analyzes the results and the system optimizes the signal in less than 0.002 seconds, adjusting accordingly.

RANC is able to calculate the sound independently for the driver, passenger, and rear seats.

Hyundai testing revealed that RANC is able to reduce in-cabin noise by 3dB, roughly half of what is currently experienced in Hyundai vehicles.

This technology has further reaching implications. Because Hyundai will not have to rely on heavy, dense foams and carpet to help with cabin noise, they are able to lessen the amount of or remove those elements from vehicles, allowing for more passenger space and less weight. In turn, this could make vehicles more fuel efficient.

The system will be mass produced by Harman.

Hyundai Motor Group has completed domestic and American patent applications for the location of sensors and signal selection method, the core technology of RANC.

The technology will begin to be applied to an upcoming Genesis model.

This 34-carat diamond-encrusted $554,000 key fob could be yours

For when the common key fob just isn't enough, there's the Awain car key. Described by the brand as "The most exclusive car key," Alain's key fobs offer everything from a brushed titanium and anodized blue silver car key to a fob encrusted with 34.5 carats in trillion and round cut diamond.

"When I was a motor journalist, I noticed that most luxury and supercar keys were fairly non- descript and made of plastic," said Jalmari Mattila, CEO, Awain. "They didn't have the same craftsmanship or finesse as the cars they powered, which seemed like such a shame. So, with that in mind, I enlisted the help of designer Leevi Markkula and watchmaker Joakim Jokela to help me create a really beautifully crafted, bespoke and incredibly luxurious key. After two years of honing and perfecting the technical and aesthetic design, Awain and our exclusive line of keys were born."

The company offers two collections of fobs with three car keys to choose from within each collection. Grand Prix Collection models are lower end models that are named after historic race circuits: Monaco, Spa, and Suzuka. Those three models are available in eight different leather and stitching colors. The design of the keys in this collection are more understated than the others that Awain offers.

Quantum, Serenity, and Phantom models are higher-end and feature diamond designs. The Quantum model has just 345 diamonds totaling 3.6 carats in diamond while the top Phantom fob has 34.5. Serenity models have 1,250 diamonds. Buyers are offered their choice of five inner colors for their fob and Quantum buyers have three metals to choose from as well.

The Finland-based company touts the fobs as a, "functional work of art" and describes its production process as "badass craftsmanship." Grand Prix Collection keys take the company's Nordic craftsmen upwards of 20 hours to create by hand. The more expensive Prestige Collection models take upwards of 100 hours.

Prices for the pieces range from around $11,000 to upwards of $554,000 per key.

As if the price isn't limiting enough, the brand messaging on Awain's website describes the fobs as for, "an exclusive group of true global elites." If you have to ask if you qualify, you probably don't.

Ford partnering with McDonalds to recycle coffee beans, create car parts with them

Soon, you'll be able to drive away from McDonald's with your coffee in a Ford car made from the fast food giant's leftovers.

I'm lovin' it! Ford Motor Company and McDonald's are teaming up to recycle the millions of pounds of coffee chaff leftover from the fast food giant's food service. The automaker and its suppliers will use the chaff in the creation of various auto parts, including headlamp housings and hood components.

The chaff is the skin of the coffee bean that naturally comes off during the roasting process. The companies found that they could convert the chaff info a durable material that can be used to safely reinforce vehicle parts.

This isn't the first time that Ford has used recycled materials in their vehicles. A few years ago the company was touting its use of tomato skins and soy in the Ford Mustang.

How does it work? The chaff is heated to high temperatures under low oxygen conditions. Then plastic and other additives are added in turning the product into pellets. Those pellets are then formed into various shapes.

The new components created using the chaff-based compound are 20 percent lighter and require 25 percent less energy during the molding process.

"McDonald's commitment to innovation was impressive to us and matched our own forward-thinking vision and action for sustainability," said Debbie Mielewski, Ford senior technical leader, sustainability and emerging materials research team. "This has been a priority for Ford for over 20 years, and this is an example of jump starting the closed-loop economy, where different industries work together and exchange materials that otherwise would be side or waste products."

McDonald's is expected to direct a significant portion of its coffee chaff in North America to Ford to be incorporated into vehicle parts. Other involved companies include Varroc Lighting Systems, which supplies the headlamps, and Competitive Green Technologies, the processor of the coffee chaff.

"Like McDonald's, Ford is committed to minimizing waste and we're always looking for innovative ways to further that goal," said Ian Olson, senior director, global sustainability, McDonald's. "By finding a way to use coffee chaff as a resource, we are elevating how companies together can increase participation in the closed-loop economy."

They're not stopping there. McDonald's and Ford are continuing to find new ways to collaboratively use waste as a resource, while furthering their respective sustainability goals.
