Elevators and thermal power stations can be very annoying, as they often operate at any time of day or night. Even if the machines are not very noisy, the phenomenon of mechanical signal transmission, the “structural borne noise” is extremely complex to deal with and produces sometimes incredible effects. Even apparently minimally invasive machinery, such as small pumps, if rigidly connected to the walls can create extremely annoying noise levels in the home environment. Only particularly complex and detailed interventions can effectively solve these problems.
