Old fashioned radiators ought to be quiet. Is the odd noise a gurgling sound like water flowing? Perhaps the radiator needs burping? If they are like ours, there is a little protrusion into one can insert a little key that fits over the square bit in the middle, twist it, and the air in the pipes comes out, and, once the air is out, it starts to leak a bit of liquid, too (on to the bit of tissue paper we set under it in advance of opening the valve). At that point close the valve, and the radiator goes back to being its proper, quiet, self. We usually have to do this for all of the radiators in the house. Is that why yours is making an odd noise?
