Is there a good listening device that will penetrate glass windows?

If you tie a brick to any listening device, it will penetrate
a glass window.

Basically, sound will not penetrate a window. Sound can cause the
window to vibrate and you can sense that.
Stick a microphone to the window.
Use a laser interferometer to sense the window movement.
