Magical. That's what this video is. Thanks to the miracles of modern science this father, who has suffered endless noise over the years as he's reared his four kids, can wallow in the peace and tranquility of hearing sweet nothing.
For ten years he hasn't heard the calming embrace of quietness, the sanctuary of children's laughter silenced.
But a new breakthrough technology has allowed him to hear, or not hear, whatever, the beautiful sound of silence once more.
It's a beautiful heartfelt moment to witness as this poor unfortunate father's dilemma is finally addressed.
Watch as he's overcome with emotion, as you will be, when modern science gives him back something he hasn't had in years. Magi-mazing.
