1. An annular resonator comprising:
a multiplicity of perforations for installation in a combustor arrangement of a static gas turbine installation,
wherein the annular resonator is produced from refractory ceramic and comprises an outer circumferential surface which tapers conically in an axial direction,
the annular resonator further comprising a multiplicity of spring elements acting in a radial direction which is arranged on the outer circumferential surface, wherein the multiplicity of spring elements have uniform spacings from one another in a circumferential direction.
