Hearing impairment
This document discusses hearing impairment and strategies for teaching students with hearing loss. It defines hearing impairment and the three types: conductive, sensorineural, and mixed. Characteristics of students with hearing loss are described, such as lack of confidence and difficulty processing oral information. Communication methods for deaf students are outlined, including sign language, finger spelling, and lip reading. The document provides tips for instructing deaf students, such as seating them close to the teacher and facing their better ear towards instruction. Ways to assess hearing loss and resources to support deaf students are also presented.

- 18. Methods of Communication •American Sign Language (ASL): This is the primary language of people who are deaf. It consists of a combination of hand movements and positions to express thoughts and phrases. • Finger spelling: This is a manual form of communication in which the hand and fingers spell out letters of the alphabet to form words.
- 19. • Lipreading: Thisis a difficult skill used only by about 10% of people with hearing impairments. Therefore, don't assume that a deaf person to whom you are speaking can lip read. Even if a person cannot lip read, however, being allowed to see the speaker's mouth provides helpful visual cues. • Written communication ("Pad and Pencil"): This is a fairly simple way to communicate with a person who is deaf. Remember, however, that sign language is the primary language for most persons who are deaf; English is a second language, so keep your words simple.

- 22. Instruction and teachingstrategies • When appropriate, ask for a hearing volunteer to team up with a student who is deaf or hard of hearing for in-class assignments. • In small group discussions, allow for participation by students with hearing impairments. • If there is a break in the class, get the attention of the student who is deaf or hard of hearing before resuming class. • Sit the student away from noisy areas. • It may be necessary to change the seating arrangements for particular activities.

Editor's Notes
- #6 There are 360 million persons in the world with disabling hearing loss This is 5.3% of the world’s population - 32 million of these are children. Disabling hearing loss is defined as: adults (15 years and older): hearing loss greater than 40 dB in the better hearing ear; children (0 – 14 years of age): hearing loss greater than 30 dB in the better hearing ear.
- #7 There are many psychological effects to hearing loss, including frustration, withdrawal, and depression. Trouble communicating with others creates a strain on relationships and a loss of esteem. It’s far better to deal with hearing loss than to pretend it isn’t happening—or to ignore the effect it is having on those around you.
- #8 The truth is, hearing loss happens gradually and the signs are subtle at first. Our own built-in defenses and ability to adapt make it difficult to self-diagnose. A simple hearing test can help you gain insight, while professional screening can provide a more definitive answer.
- #9 Hearing aids can be a great help to many people who are deaf or hard of hearing, but they cannot restore hearing that has been lost. About two million people in the UK use hearing aids, but it is estimated that a further four million could benefit from them. While analogue hearing aids merely amplify sound, digital hearing aids are also able to convert it into information that can be 'processed' by a tiny computer. This means that they can be tailored to suit an individual's hearing loss. Background noise can be a problem, as hearing aids tend to amplify everything. Although digital hearing aids are better equipped to deal with background noise, they cannot cut it out entirely. All aids work best when their wearers are having one-to-one conversations in quiet environments.
- #10 People who are deaf and hard of hearing may be able to understand what you are saying some of the time, but not always. This can be confusing, but there are various reasons why it happens. Depending on their degree and type of hearing loss, people may be able to hear some sounds at certain pitches, but little else. Lipreading requires intense concentration. This means that someone who relies on lipreading has to concentrate hard all day and may not be able to continue when they are tired. Other people with hearing loss use hearing aids. These work best in quiet environments across a distance of no more than 1.5 metres and in one-to-one conversations. If there is noise or several people talking, or even a windy day, the hearing aid user might need the help of assistive devices like induction loops to eliminate background sounds.
- #11 Noise is a cause for concern in both, developed and developing countries. In many countries, excessive noise has become the most compensated occupational hazard. The risk of social noise, such as, music and entertainment devices, is increasing globally among young persons.
- #12 American Sign Language (ASL) is the language of many people who are deaf. Some people who are deaf use one or more of a variety of communication systems based on the English language. Sign language facilitates communication with deaf people Deaf and deaf-blind persons often use sign language. Sign languages differ across cultures, but they are legitimate languages, with their own vocabulary and grammar. Family members, medical professionals, teachers and employers should be encouraged to learn signs/sign language in order to facilitate communication with deaf people.
- #13 Hearing loss is a sudden or gradual decrease in how well you can hear. Depending on the cause, it can be mild or severe, temporary or permanent.
