INTRODUCTION TO AUDIOLOGY (SPHS 1100) WEEK 7 POWER POINT TOPICS  ASSISTIVE DEVICES FOR HEARING IMPAIRED  AUGMENTING DEVICES  TRANSFORMING DEVICES

GOALS and OBJECTIVES GOAL Students will learn about different treatment options available for hearing impaired persons. OBJECTIVES  TLW identify different technology options which can be used with hearing impaired people.( cognitive)

ASSISTIVE DEVICES  Apart from hearing aids, there are other assistive devices that help people with hearing loss. There are two general categories of Assistive Listening devices such as a. Augmenting devices/systems b. Transforming devices/systems

ASSISTIVE DEVICES AUGMENTING DEVICES/SYSTEMS  These devices amplify sound and increase signal to noise ratio. Examples of augmenting devices  FM systems  Infrared systems  Induction loop system  Audio-visual FM systems

ASSISTIVE DEVICES TRANSFORMING DEVICES/SYSTEMS  These devices convert speech in to text. Examples of Transforming devices/systems  Realtime captioning  Face to face communication systems  Telecommunication device for the deaf (TDD)

AUGMENTING DEVICES/SYSTEMS FM SYSTEMS

AUGMENTING DEVICES/SYSTEMS FM SYSTEMS  Frequency Modulation systems use radio waves to transmit sound from the sound source to a receiver worn by a person who is hearing impaired.  The FM system can be fit to behind-the-ear hearing aids with special snap-on boots that pick up sound directly from a microphone.  The microphone can be set up in front of the person speaking or worn around the speaker’s neck.  They are helpful to enhance signal to noise ratio and are portable and easy to take from one classroom to another classroom.

AUGMENTING DEVICES/SYSTEMS INFRARED SYTEMS

AUGMENTING DEVICES/SYSTEMS INFRARED SYTEMS  These systems utilize light waves to transmit sound from the transmitter to a special light sensitive receiver.  The signal can be broadcast to a whole room through speakers or a person can wear an individual receiver.  They are often used in the home with TV sets.  The benefit of these systems is that they only work in the room where the transmitter and receiver are located resulting in fewer issues with cross-over.

AUGMENTING DEVICES/SYSTEMS  INDUCTION LOOP SYSTEM

AUGMENTING DEVICES/SYSTEMS INDUCTION LOOP SYSTEM  Induction loop system utilize electromagnetic energy to transmit the signal.  These systems can cover a small area with a loop placed under a rug or permanently installed within walls or ceiling of large areas like theaters, churches and auditoriums.  A Telecoil is needed within the hearing aids to use this system

AUGMENTING DEVICES/SYSTEMS AUDIO-VISUAL FM SYSTEMS

AUGMENTING DEVICES/SYSTEMS AUDIO-VISUAL FM SYSTEMS  They facilitate speech-reading for students who are oral-deaf or hard of hearing.  Audisee is an good example of this device.  The Audisee is composed of a dual transmitter worn on a speaker with a microphone for the FM component and camera for visual component.  The voice and live images are transmitted wirelessly to the student with a monitor on their desk to see the teacher’s face and receiver to hear the voice.

TRANSFORMING DEVICES/SYSTEMS REAL TIME CAPTIONING

TRANSFORMING DEVICES/SYSTEMS REAL TIME CAPTIONING  Real time captioning provides a typewritten account of all verbal information presented within a lecture, meeting, discussion or presentation.  A trained captionist will transcribe the words by using a keyboard, in to text displayed on a monitor, screen or laptop computer used by deaf students.

TRANSFORMING DEVICES/SYSTEMS Some of the examples of real time captioning devices are CART ( Communication Access Real Time Captioning)  Provides a word-for-word transcription using a stenotype machine, laptop computer and real time software. CPRINT  It was developed by the National Technical Institute for the Deaf (NTID), a college of Rochester Institute of Technology(RIT) as a speech to text communication access system.  This system condenses information using a meaning-for- meaning translation.

TRANSFORMING DEVICES/SYSTEMS REMOTE CAPTIONING  The captionist will transmit the text to the consumer by using a modem, internet or some other data connection so that he need not be physically presented and the user can listen in using a cell phone or computer microphone.

TRANSFORMING DEVICES/SYSTEMS FACE TO FACE COMMUNICATION SYSTEMS

TRANSFORMING DEVICES/SYSTEMS FACE TO FACE COMMUNICATION SYSTEMS  They provide assistance when short, one-on-one conversations are needed.  These devices have two portable battery operated keyboards that have wireless connection that allow deaf people to communicate with teachers instantly through type written messages.  UbiDUO is an example of such device.

TRANSFORMING DEVICES/SYSTEMS TELECOMMUNICATION DEVICE FOR THE DEAF (TDD)

TRANSFORMING DEVICES/SYSTEMS TELECOMMUNICATION DEVICE FOR THE DEAF (TDD)  It is also known as teletype machine (TTY).  The user can place phone calls using text through a regular phone line.  It has a keyboard with a text screen.  A user either needs to connect with another person that has a TDD or use a relay service that can convert the text in to voice for the hearing listener receiving the call.  Different models are available with different options such as printers, answering machines and memory to save text or messages.
