The loud hum that you hear is probably a 60 Hz. hum. It is caused by induction from an adjacent power feeder. When electrical feeders lay parallel to each other, the electrical magnetic field caused by the current flowing in the power conductor induces a field in the other parallel telephone cable set. These types of cables should not be run together but run with separation of at least 50 mm between them. The proper installation when distance separation of the cables from one another can not be physically obtained is to cross the power cable and the telephone cable at a 90 degree angle until the separation can be obtained.
