Downsizing of modern combustion engines is making the driving experience less and less emotional. The acoustic recognition value of a car—often an important customer requirement—is increasingly suffering as a result. That’s why at Areus Engineering we have developed an active sound system that synthesizes a large-volume, sports engine sound depending on vehicle parameters such as engine speed and rpm, and emits it to the outside via a loudspeaker. This allows the driver to retain the emotional experience of a powerful, sonorous-sounding combustion engine.
Thanks to our multidisciplinary teams of specialists, we combine all the added value from hardware and software development, sound design, loudspeaker technology and acoustics through to series production of the entire system under one roof. The result is a compact unit consisting of loudspeaker, housing and electronics, including a structural heat sink, which can be mounted in the vehicle to save space.
In cooperation with STMicroelectronics, a fully integrated system was developed around the STA1079 microprocessor from the powerful Telemaco2 series, which handles both the central control of the system and the audio signal processing. The engine sounds generated in the DSP are output to the loudspeaker by the FDA2100LV digital power amplifier with up to 120 W power. Power management for the logic section is handled by ST’s L5963.

The Areus Bluetooth Low Energy module embedded on the circuit board and a specially developed app allow various engine sounds to be called up, the volume to be changed, or a variety of information about the operating status of the car and the ActiveSound generator to be read out by means of a smartphone.
