Abstract
An acoustic device for a gas turbine combustor includes: a first region positioned at a downstream side of a combustion cylinder, the first region existing at a position which is at least one of a pair of positions across the combustion cylinder in a radial direction of the combustion cylinder; a pair of second regions whose axial-direction position with respect to the combustion cylinder overlaps at least partially with the pair of positions, and whose circumferential-direction position with respect to the combustion cylinder is different from that of the pair of positions, the pair of second regions existing at positions across the combustion cylinder in the radial direction; and a third region positioned at an upstream side of the first region and the second region with respect to the combustion cylinder.
