This question always comes up and everybody is always quick to assume its a water hammer. The previous two answers are correct. The fill valve/ballcock is partially clogged where the water flows through. Go to a hardware store and get a good fill valve. The fluidmaster is a pretty good brand. Replace your fill valve and your problem is more than likely to go away

Water hammer in most cases is caused by a loose pipe in the wall.
However, you can probably stop the problem if you change to an instant on, instant off ballcock like a Korky Quikfill, or a Fluidmaster 400A
The Korky is the better one, but the Fluidmaster is more abundant and easier for you to find.
Fluidmasters crust up between the float and the post, unless you are in a good water district.
If you have the kind of ballcock that has the float ball out on the end of a rod, what is happening is starts the loose pipe to shaking and hammering as the ballcock slowly begins to fill the tank and slowly stops.
If you ever do a remodel and have to open up the wall, don't forget to secure the water lines with 2 hole straps that are sized to fit the pipe.
You could install a hammer arrestor under the lavatory where it would be inseen, on the cold water side, but that's not a for-sure fix. If the lav is right beside the toilet, it just might work.

Sounds like the ballcock is going bad. The ballcock is the valve in your toilet that lets the water in, and it can become partially clogged with just a little bit of debris and not close properly until enough pressure is put on the float. Take the top off the toilet and flush. As the water leaves the tank the ballcock will open. You can raise the float up and down and see if the noise is effected by this. If not check to see of the valve at the wall will effect the noise. Turn the valve back and forth to loosen it. Leave the valve all the way open. If the noise is coming from the toilet and only sounds when the toilet is filling it sounds like one of those two valves need attention.

Fit a new ball valve as the first step, they wear and can become noisy. If possible fit a few more clips to the pipe. It may not be supported well enough. If that fails you may need to fit or have fitted a small anti knocking device. This is a sealed tank the size of a cup and is fitted into the pipework pointing along the pipe to take up the hammer effect. Not a very expensive part but must be correctly fitted to work. You may also want to consider reducing the flow by shutting down the incoming mains tap or maybe even fitting a pressure reduction valve.

It is "water hammer". Try this simple fix. Turn off the main water valve to the house, and open all the faucets, until all the water is drained out. Next, close all the faucets, and open the main water valve. This should help reduce the problem. You might have to install some mechanical shock absorbers, providing there aren't any in your system. Plumbers know that a closed system relies on air in the system, but if a non plumber piped the house, provision for this problem, may have been overlooked. Good luck!

I would say that you have a bad fill-valve. Purchase a Fluidmaster 400A fill-valve at a Home Center or hardware for under $10. The included instructions for installation are very simple and it's an easy job.

Difficult to diagnose without seeing the problem but it sounds a bit like "water hammer" which is caused by a valve opening and closing quickly against water pressure. Could be caused by a faulty ball valve in your toilet cistern.
I doubt that it is an airlock in a pressure fed cold water supply.

Certainly sounds like water hammer, locate the area of the vibration and clip the pipes to the wall/joist or a solid surface, that should cure it.

Not knowing what type of water system you have, this may or may not help, I had a similar problem with a sink and it was caused by the pressure switch being set incorrectly and shutting on and off rapidly.
