External Electronic Sound Synthesis

December 3rd, 2014 Posted by products No Comment yet

The Challenge

For decades, vehicles have been a part of our daily lives. We know what they are supposed to drive like, how they react and what they should sound like. With the significant increase in sales of fully electric and hybrid vehicles, we are witnessing a change in the acoustic experience in and around a car. The silence of the electric powertrain means that pedestrians miss familiar acoustic cues warning them of an approaching vehicle. With an electric vehicle, they can no longer rely on sound to determine how fast a vehicle is approaching and how close it is.

The Solution

In order to improve pedestrian safety around electric and hybrid vehicles, the HALOsonic® external Electronic Sound Synthesis (eESS) technology creates a specific electronic sound, projected from speakers at the front and rear of the vehicles, giving an early warning to pedestrians that a car is approaching. The volume and characteristics of the eESS signal are actively controlled to inform pedestrians of the vehicle’s speed and location, thereby further enhancing pedestrian safety.

The Benefits

  • Safety: The new active system is optimized to operate in urban environments with the greatest risk of a collision with pedestrians, especially high-risk groups such as the elderly, children, cyclists, and particularly the blind and their guide dogs.
  • eESS helps automakers comply with governmental safety regulations.
  • The sound of a car engine is an integral part of the experience behind the wheel and plays a crucial role in defining the DNA of the car. eESS is capable of creating custom-designed engine sounds, thereby helping to retain an OEM-specific (Original Equipment Manufacturer) sound DNA for the car.

Internal Electronic Sound Synthesis

December 1st, 2014 Posted by products No Comment yet

The Challenge

When it comes to cars, sound plays a huge part in the choices people make. The way a car door sounds when it is closed and the way the engine roars when you’re hitting the accelerator can make or break a sale. In striving to reduce the environmental impact of cars with combustion engines, OEMs (Original Equipment Manufacturers) are developing “downsized” engines with smaller displacements, fewer cylinders and turbochargers all of which impact the original engine noise.

The Solution

HARMAN engineers have set out to improve the sound of the various propulsion concepts, making the engine sound mightier than it actually is. To improve the driving experience, the HALOsonic® internal Electronic Sound Synthesis (iESS) technology enables sound contouring inside the car by creating speed-, acceleration-, and throttle-dependent sounds through the standard speaker system. The system delivers improved engine feedback and makes drivers feel connected to the car they drive.

The Benefits

  • iESS helps synthesize an exhilarating engine sound that adds a very emotional element to the overall driving experience.
  • It helps reinstate original engine sound in case of sound loss due to OEM features such as downsized engines and the use of turbochargers.
  • iESS offers multiple engine sound modes (for example normal, moderate and sporty engine sound) for the same car, thereby enhancing car occupants’ emotional experience.
