Abstract (en)
[origin: EP3242292A1] A sound damping device comprises a first flow channel device (4) and a second flow channel device (6) separated from one another with an intermediate wall (8; 8a, 8b, 8c, 8d, 8e), said intermediate wall being at least partly provided with a sound attenuating means (9), wherein said first flow channel device (4) has a first inlet (5a) and a first outlet (5b) for a first flow and said second flow channel device (6) has a second inlet (7a) and a second outlet (7b) for a second flow. In accordance with the invention, at least said first flow channel device (4) is configured and adapted in such a way that a dynamic pressure difference is created over said sound attenuating means (9) with respect to the second flow channel device (6).
