Most likely, you are hearing water hammer, which is a vibration caused when the high pressure incoming water supply is rapidly shutoff by the float valve in the toilet tank. This also occurs at other locations with a solenoid-controlled valve such as in a dishwasher or clothes washing machine.
A couple of solutions:
- install an anti-water hammer device (air chamber) on the cold water supply line as close as possible to the toilet tankd
- replace the float valve in the toilet tank.
A good home improvement store or plumbing shop will carry them.

Try this cheap fix. You should have two stand pipes in your attic, one hot one cold, that stick strait (12 inches) up from the highest section of pipe. Air should be trapped in there and act as a shock absorber, eventually the air is replaced by water and there is no cushion. Turn off the water inlet to the house, open all the valves and let the water drain for 15 - 20 minutes turn the water back on and when you have a solid stream turn the valves off. If this is your problem it should give you a fix for at least a while.

This is "air hammer" or air trapped in the line from extreme pressure. There are several ways to fix this but, none are easy or cheap. You'll have to access the line to repair it. I don't know how much you know but, respectfully say that you might want to have a plumber fix this problem.
You can get the "pig tail" from a Home depot for the relief valve and just put this in or, put in a piece of pipe about twelve inches high in the highest part of the pipe to absorb the air pressure when you flush. This is all it is, air pressure. It has to go someplace.

the pressure in your pressure tank may be too strong for the pipe causing a water hammer after sudden closure of valve (this happens after the tank is filled). try easing the pressure if it doesn't affect your household requirement.
on the other hand, the pipe inside the wall may be secured properly by adding more fasteners to absorb the shaking motion. otherwise, call your plumber.

"Air in the pipe", when the stock water tank valve shuts off after filling, a slight "water hammer" is made until the pressure in the pipe even's out, you can buy a unit that attaches to the plumbing that will stop this, if it is too annoying for you.

Air hammer. There is air in your pipes that rattles back and forth when the flow of water suddenly starts and/or stops. I don't know that there's much you can do about it without tearing up the wall.

Maybe you have some rickety old pipes in there that are on their way out. Better check on that!
