This microphone listens with light instead of sound. Based on single-pixel imaging, it can capture tiny vibrations on the surfaces of objects caused by sound waves and turn them into audible signals.

As a result, it could enable applications in scenarios where traditional microphones are ineffective, like conversing through a glass window.
