Is glass a conductor of sound?

Question

If a television or stereo is backed onto a window, will the sound of these devices travel more than if backed onto a solid wall?

Answer 1

This would depend on the glass. First, glass is a solid so the transmission of sound like with any other solid depends on the density and bond strengths of the solid. The bond strengths of glass are rather high and some glasses can be made with very high densities so it is possible, especially if the glass is thicker than a normal window pane, for glass to absorb a fair amount of sound. It should be noted that very high end listening devices are made by aiming sophisticated laser units at windows and based on the vibration of that window converting back to the sound produced inside. This allows the listerner to hear into a room while maintaining a safe distance.

Answer 2

Yes, since walls are thick of layers and outside walls are filled with insulation while window glass transmits sound rather nicely. You could have walked down the street and listened outside windows to test this.

Answer 3

well I know that sound travels FASTER through solid objects so I would say yes but don't take my word for that.
