They don't have a similar requirement because they get a translator who can stand next to the professor and/or take notes, and due to the ADA, it's mandated that they provide those services. When it comes to video/communications, the regulations are a bit more murky because the FCC may be involved. (There was a deaf student in my upper division math courses and I worked for a communications company with deaf coworkers for a bit.)
