Electronic Sound Synthesis

Helps attain the targeted vehicle sound
Electronic Sound Synthesis
Sound where needed

Due to the nature of the powertrain, electric and hybrid vehicles lack feedback on speed and acceleration. The HARMAN HALOsonic® Electronic Sound Synthesis solutions – internal Electronic Sound Synthesis and external Electronic Sound Synthesis – solve these issues by enabling the OEMs to deliver the targeted vehicle sound matching their brand identity.​

Whether inside the cabin or outside the vehicle, rich vehicle sound is an integral part of the experience behind the wheel and plays a crucial role in defining the DNA of a car. This holds especially true when engine sound is degraded as OEMs engage in measures such as engine downsizing and the use of turbochargers to reduce emissions and fuel consumption. Moreover, due to the silent nature of their powertrain, electric and hybrid vehicles lack feedback on speed and acceleration, which is essential for an emotional driving experience. 

Pedestrians, bicyclists and other road users who are accustomed to relying on auditory cues from vehicles to navigate around traffic, fail to hear approaching electric/hybrid vehicles. The HARMAN HALOsonic® Electronic Sound Synthesis solutions – internal Electronic Sound Synthesis (iESS) and external Electronic Sound Synthesis (eESS) – help to solve these issues, enabling OEMs to attain the targeted engine sounds reflective of their brand identity.​​

The sound you want where you want it
01

Internal Electronic Sound Synthesis (iESS)

  • Enables sound contouring inside the car by creating speed-, acceleration-, and throttle-dependent sounds through the standard speaker system

  • Advanced synthesis tools allow complete flexibility for “coloring the blank acoustic canvas” offered by todays electric and hybrid vehicle applications, in “all-electric” mode  

  • Sound synthesis during engine-off conditions on Hybrid Electric Vehicles or Range-Extended Electric Vehicles improves perception of engine start-stop events

  • ​Improved powertrain feedback makes drivers feel connected to the car they drive

02

External Electronic Sound Synthesis (eESS)

  • Advanced external sound synthesis technologies allow OEMs to define a unique external sound, matching their brand ​DNA and easily recognizable by anyone on the road​

03

Sound2Target ™

  • ​Combines Active Noise Cancellation and Electronic Sound Synthesis to simultaneously remove unwanted noise content and synthesize or augment desired sound content
