Active Sound Design - How does it work

[dmlgc116]

I'm new to ASD , it came with my 2022 X6MComp. I have read several articles on it but I'm still confused.

What I understand : it generates noise via the stereo speakers. I have a button on the console that turns this on and off. I don't have any menu options for ASD.

What I have no clue about: Does it actually produce exterior noise either by opening some flaps on the exhaust or via eternal speaker?

In my case I'm obviously not trying to be a wallflower at stop light (miss people looking over) , why would BMW do such a thing?


Thanks

After poking a few BMW organizations BMW Genius replied:

Thanks for contacting the BMW Genius Team.

A dual-branch exhaust system, designed specifically for the BMW X5 M and X6 M offers an enticing sound emanating from the pair of 100 mm tailpipes with electrically controlled flaps. The exhaust note can be softened or increased via the M Sound Control button in the center console. The Competition models’ note is further enhanced with a standard M Sport Exhaust system which provides for a more sporty sound to match the models’ increased capabilities.

The M Sound Control function changes the sound characteristics of the exhaust gas system. When sound control is switched on, the sound of the exhaust gas system takes on a sporty nature. When sound control is switched off, the sound is focused on comfort. During the engine warm-up phase, sound control does not have any effect on the sound of the exhaust gas system.
