Coordinator – Exhaust Systems, Catalytic Converters
Mr Hošinský, in what way does Dynamic Sound Boost improve the natural sound of the exhaust system?
Dynamic Sound Boost modulates, i.e. complements or completes, the original sound of the vehicle. However, this is not purely two sounds coming together. Both the original sound and the sound produced by Dynamic Sound Boost are made up of sound waves with different frequencies and amplitudes or intensities. Therefore, in some frequency ranges, mixing the two sounds can result in them coming together; in other frequency ranges, they cancel each other out whereby the sound of the vehicle is, for example, sportily tuned. In this way, the car’s acoustic character can be adapted for different driving modes (Sport/Eco/Normal/Comfort).
What is the key difference for the occupants in comparison to the Sound Generator?
The biggest difference between Dynamic Sound Boost (DSB) and the Sound Generator is that DSB has an effect both inside and outside of the vehicle. To put it simply, the DSB system is an alternative to an exhaust system with a sporty note.
What advantages does Dynamic Sound Boost have to offer?
The advantage of the DSB system is that it allows you to reconstruct the vehicle’s overall image, i.e. including the vehicle’s exterior sound, even in cars with a diesel engine, where this is not possible using the exhaust system. Another undisputed advantage is that you can control the DSB system through the in-car systems – the intensity of the sound modulation, for example, can be altered depending on the driving mode – or switch off the DSB system completely.
Does the sound from DSB come directly from the exhaust system?
The sound comes directly from the actuator in the ŠKODA KODIAQ RS. The actuator is mounted near the exhaust system’s tailpipes but is not physically connected to the exhaust system. This position is important for ensuring the correct interaction with the exhaust system. It enables the desired authenticity that corresponds with the vehicle image to be achieved.
