Abstract: An apparatus (8) for dampening acoustic pressure oscillations of a gas flow contained in part by a combustor wall of a gas turbine engine combustor (14). The apparatus (8) includes at least one resonating tube (10) with a closed end an open end (18) and a cavity therebetween. The cavity is in fluid communication with an interior of the combustor (14) such that the gas flow may flow into and out of the cavity.
