THE NOISE IS CALMED DOWN BY HARMAN

Harman improves the acoustic quality of automobile interiors by using road noise cancellation (rnc) technology, which is included in the company’s halosonic suite of noise control technologies. October 22, 2014, in both Stamford and Karlsbad — harman, the premium global audio and infotainment group (nyse:har), is expanding its halosonic suite of noise management solutions. These solutions were co-developed by the company with lotus engineering using patented active noise control technologies. harman is committed to making the driving experience safer, quieter, and more sustainable. The road noise cancellation (rnc) technology that was developed by Harman was the first of its type to be used in the automobile industry. Its purpose is to reduce the amount of unwanted noise that is produced as car tires roll over the road surface. Automakers are now able to employ materials with a lower weight and enhance their fuel economy with the help of rnc, which is already available for market application. This is accomplished without sacrificing the degree of vehicle noise. Automakers are decreasing the weight of automobiles in order to improve fuel economy and reduce the negative effect that vehicles have on the environment. This is often accomplished by utilizing less noise-dampening insulation inside the vehicle’s cabin. However, the use of lighter materials results in an increase in the amount of road noise that can be heard inside the vehicle. This noise not only reaches the interior of the vehicle (and the ears of the passengers), but it also degrades the quality of the audio experience provided by the on-board information and entertainment system. Traditional techniques for reducing NVH (noise, vibration, and harshness) have difficulty doing so adequately. Furthermore, these technologies have a tendency to increase weight, which balances out the fuel efficiency benefit of employing lighter materials. With this most recent innovation from Harman, both drivers and passengers will soon be able to anticipate a more peaceful voyage. The road noise cancellation solution (rnc) that is included in the harman halosonic noise management suite works to identify and eliminate unwanted road noise. This, in turn, makes it possible to improve vehicle weight and handling without affecting the amount of noise that is produced inside the vehicle. Within the realm of the automobile sector, the RNC solution is the very first of its type. The concept relies on the use of “anti-noise” in order to mitigate the effects of traffic noise. The chassis of the car is outfitted with accelerometers so that the rnc system may be implemented. These accelerometers allow the system to measure the connection between the vibrations coming from the road and the noise that is produced within the cabin. After then, the patented algorithm in the controller generates inverse sound waves, which then travel through the car’s audio system in order to cancel out the noise that was generated by the road’s induced vibration. In addition to this, it is able to deal with the broadband nature of road noise, which consists of a large spectrum of frequencies. The halosonic rnc solution has the ability to lower the peaks of the noise over the desired frequency range, which results in a quieter experience for the driver and passengers within the car. Through the use of harman’s unique real audio technology, the company’s rnc system is able to guarantee that only undesired engine or road noise is suppressed, while simultaneously maintaining music signals in a comparable audio spectrum. “we’re pleased to be pioneering these novel solutions for noise control inside and outside the car with halosonic, of which rnc is a vital element,” said Michael Mauser, President of the Harman Lifestyle Division, in reference to road noise cancelation. It is more crucial than ever for today’s drivers to have an uncompromised acoustic experience, and less noise means drivers are less likely to grow weary or distracted. By removing disruptive road noise from the equation, we are able to give manufacturers with increased chances to use lightweight materials without the danger of compromising the sense of quality and harmony inside the vehicle. “lotus engineering has many years of experience in developing vehicles, not only for the world-renowned lotus cars but also for its global engineering client base of car companies around the world,” says colin peachey, group chief engineer -controls and electrical at lotus engineering. “lotus engineering’s global engineering client base includes car companies from all over the world.” lotus have a profound understanding of the dynamics as well as the noise performance of chassis systems. Indeed, active noise control was a spin-off technology developed by Lotus after the company pioneered active suspension for its Formula One cars in the 1980s. Over the years, Lotus has been a pioneer in the area of advanced research and development of technologies for automobiles of the future. The halosonic system is a collection of noise control technologies that, when combined, reduce the amount of background noise and increase the quality of the sound both inside and outside of the vehicle. In addition to real-time noise cancellation, the halosonic system also includes engine order cancelation (eoc), as well as internal and external electronic sound creation. external exhaust sound system, also known as external ess (eess), is primarily responsible for the generation of sound in hybrid and electric vehicles. It creates the authentic sounds that drivers and pedestrians are familiar with from combustion engines, which improves safety for drivers as well as other road users. The purpose of the internal exhaust sound system, also known as iess, is to develop one-of-a-kind sound characteristics for automobiles and to shape and emphasize the sound of the engine. harman develops, produces, and distributes top audio, visual, infotainment, and integrated control systems for the automotive, consumer, and professional sectors.
