Sound absorber for railway wheels. Sound absorber for a railway wheel, comprising a casing (2) to which one or more microperforated panels (1) or MPPs are anchored, in such a way that the air plenum between the internal faces of the casing and each one of the MPPs is chosen so that the desired frequencies and absorption coefficients are achieved. The housing (2) is fixed to the wheel (8), preferably on the face opposite to the flange (that is, between the wheel and the observer), through a ring (5) coupled to the wheel hub by means of clamping or threaded joint (6-7) or adhesive or all these methods together.
