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 tonight's episode (8 p.m. on ABC Family) 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.
Subtitles, which are typically sprinkled throughout "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."
"It's a risk," said Leclerc, who has an inner ear disorder, Meniere's disease, that can cause hearing loss and vertigo.
"A big risk," Matlin said through a sign language-interpreter. "But it's going to be an eye-opener. I'm very proud to be part of this risk-taking, history-making episode."
Matlin knows about making history. She was the first -- and remains the only -- deaf person to receive an Academy Award acting trophy, honored as best actress for 1986's "Children of a Lesser God."
The "Switched at Birth" episode pivots on another key moment for the deaf community: A 1988 student protest at Gallaudet University in Washington, D.C., that ended the unbroken succession of hearing presidents at the school for the deaf.
For fictional Carlton High School (inspired by real-life LA school, Marlton), more is at stake: The school faces closure because of funding cuts, which means its students will be "mainstreamed" with hearing teens.
It mirrors a real-life trend caused by budget constraints, Leclerc said. There's also an increasing number of children being given cochlear implants to counter hearing loss, itself a controversial issue, according to series creator and executive producer Lizzy Weiss.
The prospect is dreaded by the Carlton students, either because they've felt the sting of being an outsider or because they treasure being part of a deaf-oriented school.
"Deaf people feel that moving into the mainstream chips away at their community, which is about language and culture," said Jack Jason, Matlin's longtime interpreter.
With Daphne as the driving force and invoking Gallaudet, students mobilize to take over the administration building and demand Carlton's survival. The conflict's ending will wait for the March 11 season finale.
The uprising panics parents and puts relationships at risk, including that of Daphne and Bay Kennish (Vanessa Marano), the switched-at-birth characters of the title who have come together as teenagers from two very different households.
To avoid overloading viewers with subtitles the story was designed to be highly visual, Although some moments depict the pitfalls of being a deaf person in a hearing world, Weiss said, that's balanced by positive aspects.
