Accessible Technologies for People With Hearing Loss

People who are deaf or hard of hearing need access to audible information.  This may be:

  • part of a computer interface (such as alerting tones)
  • a movie sound track
  • a voice conversation on the phone

This article covers some of the accessibility solutions for both groups of users.

Computers

Computers usually have error and alerting tones, and both Windows and Macintosh have a setting that flashes the screen whenever the sound is played.

Accessible Options for Art, Music, and Other Creative Activities

Creativity software can help users bypass the most difficult physical, sensory, and cognitive aspects of making art, while enabling expression and exploration. While there is not much high-tech hardware or software for making art specifically made for people with disabilities, there are a variety of mainstream options that can be put to this purpose. Many of these are particularly relevant to people with dexterity disabilities that prevent them from holding a paintbrush or strumming a guitar.

This article covers some of those options in:

  • Painting/Drawing
  • Making Music
  • Photography
  • Video and Animation

If you already have a creativity application, examine the interface, documentation, and online resources; you will usually find at least some of these usability and accessibility features:

Creating Captioned Video

Adding captions to video is easier than it seems, and it's getting easier all the time.  The process consists of 2 or 3 elements:

  • The text of the captions, which should be an accurate transcript of what is said in the video, plus sound effects
  • Timing information, so the right caption shows up at the right time
  • Optional formatting information about where the captions appear on the screen, font, color, etc. 

This article covers the basic steps of adding captions to a video you are creating. In some cases the steps will depend on the video production system you are using.

Audio Information Resources

People with visual or cognitive impairments can access materials in alternate formats such as large-print, braille and audio. Audio is a popular medium because it works with so many portable devices such as mp3 players, e-book readers, smartphones, and laptops. It's really a mainstream way of distributing content that people with disabilities are using, rather than a specialized channel.

Almost all types of content are available, although publishers may restrict access to some materials.

RoboBraille is a free web-based or email service that will convert digital text documents into mp3 audio files. Your file can be a .doc, .docx, .pdf, .txt, .xml, .html, .htm, .rtf, .epub, .mobi, etc..

Captioning

Captions display the dialogue, narration, and sounds of a video program.  Captions can be found on broadcast programs, DVDs, online, or on any other video technology. They are used by viewers who are deaf or hard of hearing, and by people who are learning the language or who benefit from hearing and seeing the content at the same time.

This article explores the basics of captions.  There are other articles here for more specific topics, including how to add captions to a video you are producing.

Real-time Transcription

You may be familiar with the use of a sign language interpreter for a public meeting, classroom, or workplace activity.  But many people with hearing loss do not use sign language.  They may need a transcription or captioning service that displays the speaker’s words on a screen, called Communication Access Real-time Transcription or CART.  

A steno typist with special input equipment and a projector or computer monitor interface provides this service.

Assistive Listening Technology

People who are hard of hearing may have trouble hearing a speaker in a public auditorium or meeting room, even if they use hearing aids or have cochlear implants.  Assistive listening technology is a way your organization can improve the quality and volume of the audio delivered to these audience members.  There are many options. 

This article will cover some of the issues and solutions.

The basic idea of assistive listening systems is that the audio signal is collected and transmitted to units that "feed" into a person's hearing aids or cochlear implant.
