Claim 1:
2. The combustor according to claim 1, wherein:
the second acoustic attenuator has a second acoustic cover that defines a second acoustic space on a radially outer side of the first acoustic cover together with a part of the first top plate;
the second acoustic cover has a second top plate which extends in the circumferential direction, is spaced radially apart from the first top plate, and defines an edge of a radially outer side of the second acoustic space, and a second side peripheral plate that extends in the circumferential direction, connects an end of the second top plate in the axial direction and the first top plate, and defines an edge of the second acoustic space in the axial direction; and
a radial distance from the outer surface of the combustion tube to an edge of a radially outer side of the fuel manifold is equal to or less than a radial distance from the outer surface of the combustion tube to the edge of the radially outer side of the second top plate.
