Zusammenfassung:	A microphone component and a method for fabricating a microphone component are disclosed. In an embodiment, a method includes fabricating a microphone component having a backplate and a membrane in a MEMS technology, forming a plurality of holes in the membrane, the holes having diameters smaller than 5 μm, choosing a value for a low frequency roll-off and a diameter of the holes in the membrane and choosing a number of holes such that the chosen value for low frequency roll-off is achieved.
