How to fix periodic ding sound on Mac Book An irritating ding sound keeps playing which is a kind of notification or alert with out any visual guidance to figure whats going wrong. 
(The situation is almost like a pilot of Boeing 747 Max who doesn't know how to turn off anti stall system. :o) )

I found some solutions mentioned here However none worked for me.

Anyone has a clue?
After a trial and error I found Chrome is causing the irritating ding notification.
