"Noisy Tabs" in Google Chrome- Detecting if sound is playing

Question

Google Chrome recently introduced the feature that allows users to tell what tab is making that "Noisy sound". What i'm interested in finding out is if this new feature allows chrome extensions to detect if a tab is making a sound.

There is no documentation of any similar feature on the chrome.tabs developer page. Is there a way that you would be able to detect if a sound is playing (Without taking a "guess" based off of the content of the page i.e if the page contains mp3 or video content)
