See Faceless with open captioning, a service provided for people with hearing disabilities who use assistive listening devices, hearing aids, cochlear implants, sign language and lip reading. This option can be beneficial to anyone with any level of hearing loss.
Open captioning is a text display of words and sounds heard during an event. The display is positioned in such a way that it is open for anyone, but is best viewed from a particular seating area. It is considered passive assistance, a service that is there to use or ignore. No one is labeled as needing the captioning, and no special equipment is required at his/her seat.
