There should be one of these in each and every building in America. It is so necessary that everyone have one that there are laws in all 50 states requiring that one of these be installed and tested regularly. Yes, I am talking about the fire alarm.

New developments in the 21st century use piezoelectric transducers to detect the sound of drywall expanding when exposed to rapid heating. This will be especially helpful when incorporated into buildings with extensive electrical systems as they have a higher risk of electrical fires.
