Is there any kind of custom event we can use for this? I am guessing the answer might be no, as screenreaders tend to work on the OS level rather than the browser level, but I might be surprised.
In the new Firefox 42, it's possible with the mouse to stop sound from a 
tab. Can you use the idea from there to implement some kind sound 
reduction ?

Best regards.
