Footfall sound on a timbered ceiling

The family living in the flat above you is really nice. However,  every move of an occupant is audible. Especially in older dwelling houses all parties (save for those on the top floor)  have tales to tell about the structure-borne noise nuisance they have to put up with

A timbered ceiling is made up of the basic ceiling structure, the floor, and a floor covering. Structure-borne sound is the sound produced when you move (e.g. walk). It also includes vibration (e.g. caused by a washing machine in operation) that enters structures such as the floor. Because of the structure-borne transmission to an adjacent room, it is perceived as a nuisance. Timbered ceilings frequently have no adequate sound insulation
