[origin: EP1559874A1] Diffuser (17) comprises a Helmholtz resonator mounted on a housing (19) and having a damping frequency that corresponds to the intrinsic frequency of the diffuser. The Helmholtz resonator is provided in the form of a Helmholtz bottle (23a) and the housing has especially a number of Helmholtz bottles, in the form of an annular, slotted Helmholtz tube extending especially along the periphery of the housing, or in the form of a slit-shaped Helmholtz opening in the housing that extends especially along the housing periphery (27). An independent claim is also included for a turbine comprising the above diffuser.
