Abstract
A Helmholtz resonator (24, 24′, 24″, 24a), which is screened in an acoustically transparent manner from the flow (S) by means of an absorption noise suppressor (36) is located on the flow duct (16) in order to suppress the low frequencies in an exhaust gas system (10) for industrial gas turbines with an exhaust gas conduit (12) and a chimney (14) which is connected to it, which together form a continuous flow duct (16).
