Drones are nothing of not noisy, and that noise is unlike almost any other piece of machinery.
It shouldn't be too hard to set up towers around the airport with sensitive speakers that can triangulate the location of a drone flying within a restricted area. From that point it can sound an alarm and/or deploy counter-measures.
