How thermal imaging helps Ford build quieter cars

Ford is using thermal imaging technology – like that used by police and military units to find criminals and enemy combatants – to hunt down and eliminate air leaks in vehicle cabins with extreme prejudice.

This enables the automaker to build quieter cars by deleting air leaks, resulting in diminished wind noise, a key element in customer satisfaction.

By creating a color-coded image of the heat signatures within a view, thermal imaging is used in numerous ways. In 2009, it was even used to screen for victims of Swine Flu by governmental agencies at airports.

Ford uses thermal imaging to show where air leaks in the vehicle design are – they show up as hot spikes revealing the escape of heated air.

"Ford is redefining our vehicles through many innovations – both features to improve the driving experience and fuel economy, and advanced new tools to help engineer better vehicles," said William Dedecker, noise, vibration and harshness engineering supervisor. "We are using thermal imaging to further improve quietness so customers can enjoy the other features our vehicles offer, such as audio systems...and even the sounds of silence."

Taking inspiration from energy companies, who use thermography to identify energy leaks in homes, Ford uses the technology to locate the leaks in their prototypes.
