1. A gas turbine combustor, comprising:
a combustion cylinder; and
an acoustic device disposed on an outer circumference of the combustion cylinder, wherein the acoustic device includes:
a first region positioned at a downstream side of the 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 of the first region, and whose circumferential-direction position with respect to the combustion cylinder is different from that of the pair of positions of the first region, 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,
wherein a thickness of the acoustic device in the radial direction in the pair of second regions is smaller than a thickness of the acoustic device in the radial direction in the first region, and
wherein a thickness of the acoustic device in the radial direction in the third region is greater than the thickness of the acoustic device in the radial direction in the pair of second regions.
