<p>A gas turbine combustor comprises: a combustor liner through which a combustion gas flows that is produced by combusting a fuel jetted from nozzles; and a first resonator and a second resonator mounted on the outer surface of the combustor liner. The second resonator is positioned on the downstream side of the flow of the combustion gas to the first resonator and attenuates combustion vibration having a higher frequency than the first resonator does. The first and second resonators are acoustic liners having housings mounted on the outer surface of the combustor liner. The resonant spaces enclosed by the housings and the outer surface of the combustor liner communicate with the inner space of the combustor liner through a plurality of acoustic holes formed on the combustor liner.</p>
