Rumble measurement is figuring out how much shaking and vibrating you are getting from a machine or a thing. It's like when you are riding in a car and your body shakes a little because of the bumps on the road. Rumble measurement is the way we measure how much the car is shaking your body.
Scientists and engineers use machines called vibrometers to measure rumble. These machines have a special sensor that can feel how much a thing is moving and vibrating, and it puts that information into a graph or a number. The higher the number or the bigger the graph, the more rumbling is happening.
Rumble measurement is important because too much shaking and vibrating can be bad for people and machines. If a machine gets too much rumbling, it can break or wear out faster, and if we are around too much rumbling, it can be bad for our health. So, scientists and engineers use rumble measurement to make sure everything is working the best it can and to keep us safe!
