It depends partly on your location but many radiator systems have bypass pipes through which water passes to and from other radiators on the same circuit - even it that particular radiator has it's valve turned off. Air in the heating pipework can cause the sort of noises you describe and can be eliminated by bleeding the air from the system See ...
You might have air in the pipework to the radiators. You can bleed air from the system's heating circuit (usually a bleed valve is present at the highest point in the pipework) and from individual radiators. Details vary depending on which side of the planet you are standing.
