| Jun 29, 2013 at 9:16 | comment | added | guru | @joshphysics: thank you for that informative post. obviously, it wouldn't be a mystery if the cause could be pinpointed - like for eg. a gust of wind or vibrations from a woofer. but there were no gusts of wind at that time, nor was i listening to loud music. your suggestion of tiny perturbations building up sounds more plausible but have such situations been studied before scientifically? are there any results available of any study done? | |

In the country, strong wind on the panes transfers pressure from their elasticity even if they are closed. And in earthquake prone regions there are always microquakes that may build up and change a metastable state to unstable. | |
