Using windows as "bass traps"?

Please explain how to use the floor to ceiling windows at the rear of my home theatre as “bass traps”.

Someone long ago explained to
me that the bass simply passes through the windows and never returns.

Does this work better with single pane than with triple-pane sealed units?

Hi Videon, An open window is a perfect absorber . Sound energy leaves and never returns. Low frequency energy will find the area in your room that has the weakest density and go right through it. However, glass moves in reaction to low frequency pressure and may produce a diaphragmatic reaction producing more noise. The surface of a window is hard and brittle and has a negative impact on middle and high frequencies that reflect off of its surface. Stay away from glass in any critical listening environment. Its more trouble than its worth.
