Crunches

The factory worker was responsible for the crunches of the plastic bottles.

The crunches of the gravel under the car's wheels filled the air.

The loud crunches of the machine could be heard from the next room.

The gravel crunches as the car drives up the driveway.

He crunches the gravel beneath his tires as he drives down the dirt road.

He crunches the popcorn in his mouth at the movie theater.
