Abstract
In a combustion chamber for a gas turbine, noise absorption is achieved over a wide frequency range with simultaneous cooling of the arrangement and low space requirement by the inner wall being formed, at least in a partial region of the inner walls by at least two perforated plates arranged essentially parallel to one another, and by the distances between the perforated plates and the geometrical dimensions of the openings being selected in such a way that a plurality of mutually connected Helmholtz resonators is formed and that, in addition, further expedients are available which act to absorb noise.
