This is vibrational noice. It is the noice (sound) that transmits through the building structure to the place where you stay. It is usually produced when some part of the structure is made to vibrate, e.g. by striking, drilling or the like, such vibration will be transmitted through the building structure to other parts of the building. Since sound travels faster in solids than in air and with comparatively less attenuation, vibrational noice could thus travel several storeys, causing much nuisance to occupants.
