During my search for assistive technologies available for the hearing impaired or Deaf this disability was often paired with blindness as well. It was explained that both of these disabilities account for the smaller part of the disabled population so maybe that is why they were often paired together. Another reason could be that a lot of times when a person has one disability it can be accompanied by another or sometimes multiple disabilities reside within one person. At any rate I concentrated on the Deaf. The Deaf community and members within consider it offensive to call them hearing impaired or to say that they have suffered a loss of hearing. They consider ASL (American Sign Language) to be their native language and English their second language. Some do not speak by choice however most of the Deaf learn to speak in order to effectively communicate with the general public.
I will move from older to newer technologies as some of the older ones will still be in use but not for long I am sure as smartphones are getting smarter every day.
In the classroom setting the interpreter was at one time the only way a teacher could communicate effectively with a Deaf or hearing impaired student. The interpreter stands to the left and a little bit behind the teacher and signs what the teacher says in sign language for the Deaf student to see and understand.
Hearing aids can be used by some students with hearing impairment however, do know that the aids amplify ALL of the sound including background noise which could still make it difficult for the student to hear the teacher. Use of FM systems (the same kind as presidential security or McDonald's drive through) where the teacher wears a mini microphone and the student wears a pair of headphones is extremely useful in these cases because the student hears ONLY the teacher.
Sidekick is a mobile communication device that allows the user to receive Instant Messages (IM) and Email. Of course this device is being replaced by the cellphone.
Video instruction and televised announcements with closed captioning can be effective tools. The student can pause or review any forgotten or missed parts of the video instruction avoiding misunderstood questions or answers due to language/communication barriers.
Photo experience books created by the student offer a visual tool to communicate personal experiences with a hearing person without the use of spoken language.
Power point presentations are great for the hearing impaired and Deaf students. It is a computer program that is offered through Microsoft. The program allows the teacher to add pictures and text to slides eliminating the need for the student to hear what is being said.
A vocalization to visualization tool is available for free through a computer program called Winamp media player. A microphone is used and auditory sound is turned into visual fireworks on the computer monitor. This is used to represent the sound that is going on in the room as well as to teach the Deaf student how to speak.
The top assistive technology by far within the Deaf community is the smartphone and texting. The junior high and high schoolers especially like this because it completely eliminates the need to speak. They can communicate clearly and just as quickly with text as their hearing peers.
All of these technologies can and are used in real world situations and like I said earlier the smartphone is quickly replacing a lot of these technologies as I type.
