rumbling

That is, until the wee hours of the morning when I heard something rumbling.

On the worst days, when staffing was at its lowest levels, the residents would sometimes shout for help as they heard my cleaning trolley rumbling past their rooms.

A whisp of a canorous clarinet or a rumbling rattle is all it takes for a kind of instant transport to a far-off time and place.

There was no escape from the onslaught of car horns, rumbling motors and pedestrians blasting music from speakers stuffed in backpacks.

The rumbling tanks came first in the display of China's new weapons.
