    摘要： A sound damping device adapted to be arranged inside a duct or a chamber, comprises a first element (40a) including at least one first wall (20a) of a first channel (12a) having an inlet (14a) and an outlet (14b), a second element (40b) including at least one second wall (20a) of a second channel (16a) having an inlet (18a) and an outlet (18b), said first and second elements (40a, 40b) together forming a stack, wherein at least a portion of at least one of said first and second elements (40) comprises an acoustic energy dissipative sheet material. In accordance with the invention, said first and second elements (40a, 40b) are arranged in relation to one another in such a way that the first channel (12a) is angled in relation to the second channel (16a).
