Technological Advances for the Deaf
Captioning is the process of converting the audio content of television broadcasts, films, videos, DVDs, live events, or other productions into text and displaying the text on a screen or monitor
Videophones are telephones with a video screen and they enable Deaf people to call each other and use sign language to communicate.
the teletypewriter (TTY) allowed Deaf, hard-of-hearing, or speech-impaired people to communicate with all types of people
Technology At Home
the TTY is a keyboard-like device that allows two people to type messages back and forth to each other instead of talking and listening, much like texting
the Telecommunications Relay Service allows a hearing person to communicate with a Deaf person through an operator who converts the text to speech or speech to text
By law, all television programs are required to have closed captioning
“Closed captions” are captions that are visible only when selected and activated. "Open captions are captions that are permanently embedded in the audio content so they are permanently visible
Captions are often produced in advance for pre-recorded material. Captions provided for live events are called "real time" captions
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard-of-hearing
The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin
Cochlear implants bypass the damaged portions of the ear and stimulate the auditory nerve directly
The implant does not restore normal hearing, but gives useful representation of sounds instead which takes time to learn
Videophones themselves aren't very popular because cellphones and webcam software (Skype or FaceTime) have the same purpose but are more adept at a lower cost.
Video Relay Services (VRS) work like this: the interpreter will sign with a deaf person through videophone and talk with the hearing person through telephone
A "Deaf" alarm clock is an alarm clock that is usually hooked up to a louder alarm, a strobe light, or a vibrating object (pillow or bed).
Louder alarms are for people with minimal hearing loss, while the strobe lights and vibrating objects are for people who have severe hearing loss
Alerting devices such as flashing lights, vibrating objects, or an increase in volume to let Deaf people know when the smoke alarm goes off, doorbell rings, baby cries, or the telephone rings

Hearing Loss Devices
Hearing aids are mechanical devices that amplify all sounds to the user
- the sounds may have distortion or be very loud depending on the severity of the user's hearing loss
Assistive listening devices (ALDs) emphasize a single signal while reducing background noise
- some are designed to be used with hearing aids or cochlear implants but others can be used alone
Pure-tone hearing tests are evaluations that are be used to determine the level of hearing loss
