Hearing impairment refers to any level of reduced hearing that affects educational performance. Total communication incorporates all means of communication including signs, gestures, fingerspelling and speech. Cued speech uses handshapes and placements to make mouth movements visually distinct. Assistive devices like FM systems, hearing loops, and augmentative communication devices help people with hearing loss communicate by amplifying sound, transmitting signals, and generating or displaying speech. The oral approach focuses on developing listening and spoken language skills through amplification and visual cues without using sign language.
