Why Google Tone?
Google Tone helps computers communicate like we do—by talking to each other. It's a browser extension that lets Chrome use your computer's speakers to produce a special sound signature for other computer's microphones to identify as a URL.
How does Google Tone work?
Google Tone turns on your computer's microphone (while the extension is on). Google Tone temporarily stores a URL on Google’s servers and uses your computer's speakers and microphone to send it to nearby computers connected to the Internet. Any computer within earshot that also has the Google Tone extension installed and turned on can receive a Google Tone notification. The notification will display the URL along with your Google Profile name and picture.
