Public-use ALDs are systems that are designed to be used on public properties including places of worship, courtrooms, theatres, and schools.

Public-use Assistive Listening Devices (ALDs)

There are many different types of assistive listening devices available for private use that can be beneficial to use in certain listening situations to overcome background noise and gain a clearer sound.

Personal Assistive Listening Devices (ALDs)

Assistive listening devices (ALDs) are devices that can be used along with your hearing aids to enhance your listening experience and provide extra help in challenging listening situations.

- Enhance hearing and sound quality in noisy or challenging listening environments
- Offer substantial hearing benefits when used with your hearing aids or without.

Subtitles are a written translation of dialogue that is displayed while the audio is playing. This can help make auditory information accessible to those who are hard of hearing or deaf. This can be also useful for people who may be unable to play the sound out loud, unable to distinguish what someone is saying, or may speak a different language than the one spoken in the audio.

Subtitles for People Who Are Hard of Hearing or Deaf

Deaf sensitivity training gives an overview of Deaf culture and effective communication strategies. Participants learn that American Sign Language (ASL) is a distinct language and may be many deaf people’s native language.

A hearing aid is a small electronic device worn in or behind the ear that can help deal with mechanical hearing problems, such as conductive hearing loss. It functions by amplifying incoming sound waves to make the vibration of the eardrum and the movement of the ossicles more likely to occur.

Hearing Aids

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.

-  A microphone, which picks up sound from the environment.
-  A speech processor, which selects and arranges sounds picked up by the microphone.
-  A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
-  An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve.

Captioning is the process of displaying text while a video is being played. Typically, the text will be a transcription of the video's audio, noting who is speaking along with sound effects and important musical cues. This helps to make films, television shows, and other video recordings accessible to those who are hard of hearing or deaf.

Captioning

There are many types of TRS available for people with hearing and speech disabilities that allow for them to communicate by telephone in a way that is equivalent to communication used by hearing people.
