I know exactly what that is. Once every 8 to 12 hours your unit enters the defrost cycle.

During defrost what happens is a heater comes on to melt frost out of your freezer coils.

This element becomes very hot. Red hot....just like a stove.

The sound is the water bouncing off the element during this cycle. It is very normal, that is a good sound. Plug it in and know your unit is doing exactly what it is supposed to do.
