Steam hammering?

Renter in an older (1920s) NY building here.

Lived with steam heat most of my life, but have moved into a unit with a radiator that makes noises I haven't heard to this extreme. This seems to happen every time it kicks on, so every hour and a half when it's cold outside.

Month plus dealing with super/management trying or pretending to try and fix. I don't have a knowledge of so when they say they've fixed leaks on intake and outflow pipes throughout the building (on the top floor and basement), I take them at their word.

The radiator is sloped toward the supply pipe and it has a vent that seems too good (loudest and highest pitched I've experienced). I am on the second floor of a 4th floor building with other functioning radiators on the other side of the apartment.

Below are some links to videos - any idea what's going on? Sound is like hitting a cast iron skillet with another one.

    Your video links come up as “not found” but from your description the pressure is too high and/or the main venting is faulty or non-existent.

    and your description of the clanging is water hammer caused by water getting or staying where it shouldn’t 

    see if the super will hire @JohnNY to tell him what to fix.

    Are your neighbors noticing the noise as well?
    Try turning the radiator vent upside down, which may keep steam from entering the radiator, which will give you some relief while you keep on insisting on a real solution to this.—NBC
