Innovative HARMAN HALOsonic Technology to Optimise Sound Experience of Fiat Chrysler Vehicle Engines
Extending its cooperation with Fiat Chrysler Automobiles, HARMAN receives a new award to equip Fiat Chrysler vehicles with Engine Order Cancellation (EOC) technology, which decreases perceptible cabin noise.
Stamford – May 21, 2015 – HARMAN International Industries, Incorporated, the premier audio, infotainment and software services company, announces a new award from Fiat Chrysler to equip vehicles with Engine Order Cancelation (EOC) technology. EOC, part of the HALOsonic suite of active noise management solutions to reduce noise and enhance sound inside and outside the vehicle, will be installed in numerous Fiat Chrysler vehicle models. The latest award extends the successful cooperation between HARMAN and Fiat Chrysler for HALOsonic sound management solutions which began with the Jeep Grand Cherokee.
EOC uses active noise cancellation technology to reduce the drone and rumble induced by the engine vibrations in the car cabin. It uses engine RPM signal as a reference to generate a sound wave opposite in phase to the engine induced low frequency noise. Error microphones mounted in the roof of the car provide adaptive feedback on the cabin noise level in order to fine-tune the cancellation, helping occupants enjoy an enhanced driving experience. By decreasing perceptible cabin noise, EOC enables automakers to pursue various measures to reduce vehicle weight as part of the move to improve fuel efficiency without impacting in-cabin noise.
Commenting on the EOC award, Michael Mauser, President Lifestyle Division HARMAN says, “Fiat Chrysler drivers obviously appreciate the enhanced sound experience in their vehicle cabins. We look forward to the opportunity to extend the number of Fiat Chrysler drivers and passengers benefitting of Engine Order Cancellation technology for quieting their car journeys.”
The innovative HALOsonic suite gained Fiat Chrysler recognition right from the outset, winning the 2013 Innovation Award from Fiat Chrysler Automobiles. This was followed by the 2014 Environmental Excellence in Transportation Award from the Society of Automotive Engineers.
In addition to EOC, HARMAN’s HALOsonic suite comprises Road Noise Cancellation (RNC) and Internal and External Electronic Sound Synthesis (iESS and eESS). The RNC technology works similar to EOC and minimises the unwanted low-frequency noise transmitted from the road surface into the vehicle cabin by generating a sound wave opposite in phase to the vibration-induced noise inside the cabin. Electronic Sound Synthesis, on the other hand, seeks to synthesise the authentic sounds of an engine, inside or outside the car. Inside the vehicle, iESS synthesises engine harmonics to provide a more intense in-cabin sound experience. Outside the vehicle, eESS – primarily used for hybrids and electric vehicles – creates authentic sounds which drivers and pedestrians are familiar with from combustion engines, thereby increasing safety both for drivers and other road users.
HALOsonic is available to OEMs and can be implemented as a complete suite or as separate components.
