In a premix burner (18) having axial or radial air inflow, in which premix burner (18) the combustion air (15) flows out of a plenum (27), arranged before or around the burner (18), into the burner (18) and fuel (12, 13) is mixed with it on the way through the burner (18), a perforated component (24) having a wall thickness (s) and openings (25) of in each case a diameter (d) and at a distance (t) apart is arranged between the plenum (27) and the burner (18), which component (24) splits the combustion air (15) flowing through into small defined jets which reunite after a certain running length (l), the ratio of wall thickness (s) to the diameter (d) of the openings (25) being greater than/equal to one, and the ratio between the through-flow area of the component (24) and the possible inflow area to the burner (18) being greater than/equal to one as a function of the type of burner.
