[b]The system then uses the vehicle's audio system to produce a signal acoustically opposite to the undesirable sound and effectively reduce it. [/b]EHC allows for a high level of customization and control for the NVH engineer, while providing effective and efficient noise cancellation. Image of EHE chart Provide desirable, linear sound Bose Engine Harmonic Enhancement (EHE) also works with the vehicle's audio system. Using information from the engine and vehicle, it generates a complementary signal to enhance or modify the spectrum of select powertrain sounds, to provide refined and desirable—smooth or sporty—powertrain sound inside the cabin. EHE can help create more linear sound while mitigating or masking sound anomalies. It offers broader sound control than traditional methods and enables more precise control. Control for multiple modes Rapid Mode Transition (RMT) module is an optional, add-on feature for Bose EHC or EHE that provides additional capabilities for managing complex noise challenges associated with variable powertrain and cabin modes. When multiple tuning modes are required to achieve a desired powertrain sound character (cylinder deactivation/reactivation, hybrid operation, etc.), the transitions between modes may require special control. The Bose RMT module offers additional control parameters to the engineer for a more seamless sound experience.[/i] http://www.motorauthority.com/news/1089316_bose-to-offer-noise-canceling-tech-for-all-cars Dec 24, 2013 [i]Many performance car fans are rather fond of the noises their vehicles make, but there are times when you just wish a car would shut up--the drive home after a long day at work, perhaps, or while listening to the drone of your muffler on a highway drive. For such eventualities several companies have developed noise-canceling technology, and audio specialists Bose have announced a new chip that allows the technology to be incorporated into any vehicle--not just those with Bose audio systems. According to Autoblog, a new NXP semiconductor chip allows all manner of systems to be incorporated into AM, FM and DAB tuners. As well as running the various features of modern in-car infotainment packages, it can also run Bose's noise-canceling technology.[b] Active noise canceling has the ability to take the wavelength of unwanted sounds such as engine and powertrain noise and play back noise at opposite frequencies--so those inside the car enjoy reduced noise over those frequencies. That doesn't just mean loud noises from your exhaust, but unpleasant sounds associated with engines meeting modern emissions and fuel standards, with unusual harmonics and other odd sounds.[/b] The system does rely on your vehicle's audio equipment working at the frequencies required by the technology, and your audio head unit must incorporate the appropriate NXP SAF775x car radio integrated circuit. But aside from those limitations, it should work in anything. Until now, the system was only available in models from Buick, Cadillac, Chevrolet and Infiniti, which used original equipment sound systems by Bose. The company also says the sounds are programmed for each vehicle, which means a whole range of vehicles could get the option of a quieter, more pleasant cabin.[/i] http://www.autoblog.com/2013/12/22/bose-noise-cancelling-in-new-cars/ [i]Bose® Active Sound Management Software for Noise Cancellation in Cars Now Available on Chip from NXP Semiconductors FRAMINGHAM, Mass., December 17, 2013 --(BUSINESS WIRE)--Today, Bose announced it will offer its industry-leading noise-management capabilities to auto manufacturers as a software solution integrated on a chip from NXP Semiconductors N.V. Through an engineering collaboration with NXP, vehicles without Bose® speakers and amplifiers can now use Bose Active Sound Management technology to cancel unwanted engine and powertrain noise in a car's cabin. The Bose software solution will operate in any vehicle using a head unit equipped with NXP's SAF775x car radio integrated circuit, and any sound system that performs in the frequency range necessary for active noise cancellation. The Bose/NXP solution provides an easy, efficient approach for controlling engine and powertrain noise by using existing sound system designs and eliminating the weight and cost of traditional noise management. The Bose noise-cancellation software is customizable; Bose engineers will tune it to the manufacturer's requirements, providing comprehensive, scalable support for the technology during vehicle development, pre-production and post-production. "Bose is an industry leader in Active Sound Management technology, helping car makers efficiently control the way their vehicles sound inside the cabin," said Marc Mansell, general manager of the Bose Automotive Systems Division. "Now, we can offer that capability to new customers in a new way -- on a chip -- making our proven expertise even more accessible." "The new SAF775x family of car radio and audio one-chips opens up a new field of audio applications," said Torsten Lehmann, senior vice president and general manager, car entertainment solutions, NXP Semiconductors. "We're proud to bring the benefits of Bose noise management to our broad base of automotive customers and further strengthen our No. 1 position in the automotive infotainment semiconductor market." Solving Noise-Related Challenges Many of today's cars have a variety of systems and components, including high-performance and high-efficiency powertrains that produce unfamiliar and unpleasant sounds. To address this, automotive engineers need to create solutions that will refine the sound in the cabin. But this adds time and cost to the development cycle. Bose developed Active Sound Management technology as an alternate approach, drawing from more than 30 years of research in automotive acoustics and noise cancelling for aviation, military and consumer applications. Unlike conventional noise-management systems that rely on mechanical solutions, Bose Active Sound Management uses proprietary signal processing algorithms to replace heavy, space-consuming parts, such as acoustic insulation, mass dampers and active exhaust valves. But until now, Active Sound Management was only available in cars with Bose sound system hardware, including models from Buick, Cadillac, Chevrolet and Infiniti. The Bose/NXP solution extends the technology capabilities to a wider range of car makers and models. Targeted Noise Cancellation Bose Active Sound Management targets a narrow band of low-frequency engine sounds in zones throughout the cabin. Using information from cabin-mounted microphones and engine information from the vehicle's data bus communication system, a Bose algorithm continuously monitors and measures noise, and sends acoustically opposite sound signals through the vehicle's speakers to cancel targeted noise. The system is programmed specifically for each vehicle, responding only when needed.

There will be more EHC equipped Audi models in the future but the A7, several Cadillac's, an Infiniti and a Mazda vehicle are the only models on the market at this point in time. [/i] [/quote]
