FRAMINGHAM, Mass.--(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.

About Bose Automotive Systems
In the early 1980s, Bose engineers created the world’s first factory-installed premium sound systems for General Motors luxury automobiles. Unlike conventional or aftermarket automotive systems, these Bose systems were specifically designed and tuned for the particular model in which they were installed, and helped transform the automobile from a hostile listening environment into a haven for music enjoyment.
Since then, Bose has developed proprietary speaker designs, advanced amplification and signal processing technologies, exclusive analysis and design tools, and technology for managing engine and powertrain sounds inside vehicles, all based on a heritage of research and engineering. And in 2013, Bose celebrates an important milestone as the only audio company to deliver 30 years of continuous innovation for auto manufacturers worldwide.
Today, Bose automotive sound systems are recognized globally as the industry benchmark for performance and customer satisfaction.
