When a truck rumbles by a building, vibrations can travel up to the structure's roof and down again, generating transient tremors through the intervening floors and beams. Now researchers have developed a computational model that makes sense of such ambient vibrations, picking out key features in the noise that give indications of a building's stability. The model may be used to monitor a building over time for signs of damage or mechanical stress.
