The hammering sound is due to water hurrying with the water pipes and then being turned off rapidly. The water stops quickly and then attempts to press back up the water pipes. This triggers the water pipes to bang the wall surfaces.

The water hammer needs to be taken care of as soon as possible. It’s not most likely to damage the wall surfaces yet will certainly rupture the water pipes and create flooding.

One of the most common reasons is dishwashers and washing machines with automated shut off the water quickly. Closing any kind of tap off quickly could trigger a water hammer. Toilet shutoff could create a water hammer to establish where the trouble is and set up a Water Hammer Arrestor in between the home appliance or tap and plumbing.
