Such insights are a staple of the ABC Family drama, a TV rarity that puts deaf characters, played by deaf or hard-of-hearing actors, at the center of the action.

But Monday’s episode takes it a bold step further: Save for a few spoken words at the beginning and the end, it is silent. The actors’ hands do the talking with American Sign Language, even rapping together in one gleeful sequence.

“Switched at Birth” episodes, keep the viewer clued in. But when a deaf character is confused because she can’t hear something vital, the audience is too. It’s powerfully disconcerting.

The cast, including Oscar-winner Marlee Matlin as the school counselor, are excited about what they see as a grand experiment and eager for viewer reaction.

“This is an opportunity for the hearing person to watch at home and try to experience it,” said Katie Leclerc, who stars as deaf teenager Daphne Vasquez. “It’s not exactly the same, but maybe you can try to imagine what your everyday life would be like.”
