Noise in the car? Here is the solution
HARMAN and Hyundai have developed a technology that can eliminate the noise coming from the road or by the tires …
It’s called Road-Noise, Active Noise Control (in some parts) and is a system capable of reducing the noise level inside the passenger compartment, such as the one that comes from the tires and the road surface. Put it to the point, HARMAN International, a subsidiary of Samsung Electronics, which focuses on technologies related to the automotive markets, in collaboration with Hyundai Motor. A technology that promises sparks and that he is already at the edge of Genesis GV80, The Suv the Korean presented the 15th of January in the motherland.
On the other hand, how can we deny that the noise inside the car is one of the fundamental elements in the choice of buying a car?According to a study commissioned by HARMAN, end-users have indeed reported that the road noise is the largest distraction hearing for motorists.
The point is that today, the end customers require more handling of the vehicle, improved fuel economy, a stiffer suspension and wide tyres to low profile. The downside is that measures to respond to these needs and offer multiple paths for the transmission of unwanted noise through the structure of the vehicle, creating ultimately a hum inside the passenger compartment, which is both distracting that tiring. The application of conventional methods of passive Noise, Vibration and Harshness (NVH) to reduce the noise of the busy cities, significantly increases the weight of the vehicle, with an additional negative effect on fuel economy and emission levels of CO2.
Here’s the solution. The control processor RANČ using the reference signals received from the acceleration sensors strategically placed along the suspension and along the frame to predict the noise transferred into the cockpit, and to generate a wave from noise in real-time.
The calculation time and the transfer speed of the signal are optimized to allow the analysis of intrusive noise and the generation of noise in a few milliseconds, thus preventing the noise from reaching the ears of the passengers. The mics of error constantly monitor the performance of the system in every seat to ensure a more pleasurable drive for all passengers. The rest you know: when you turn on a car the sound is one thing, the sound another.
