  1. Regan Doiel & Jessica Kaaz Hearing Loss

  2. The Hearing Process • Brain translates impulses caused by sound waves into meaningful messages. • Allows communication through the “telling-listening” process. • Facilitates sharing of ideas and emotions, and membership in mainstream society.

  3. People Who are Deaf.. • Profound hearing loss • Very little, even with aids • Restricted ability to communicate • Feel part of cultural minority—the Deaf culture

  4. Three Groups • Congenitallly Deaf—present at birth • Prelingually Deaf—occurs before language development • Postlingually Deaf—occurs after age 2 or language development

  5. Types of Hearing Loss • Conductive Hearing Loss—loss in the outer/middle ear • Sensorineural Hearing Loss—loss in the inner ear • Mixed Hearing Loss—both sensorineural and conducive

  6. Degree of Hearing Loss • Mild—hear some speech sounds but soft sounds are hard to hear • Moderate—hear almost no speech at a normal level • Severe—hear no speech at a normal level and only some loud sounds. • Profound—will not hear any speech and only very loud sounds

  7. Degree of Hearing Loss • Degree of hearing loss refers to the severity of the loss.

  8. Also described as.. • Unilateral or Bilateral—One or both ears • Pre-lingual or Post-lingual—Before language acquisition or after • Symmetrical or Asymmetrical—Same or differing degree and configuration of hearing loss in each ear • Progressive or Sudden—Becomes worse over time, or happens quickly • Fluctuating or Stable—Changes over time, or sometimes getting better, sometimes getting worse • Congenital or Acquired/Delayed Onset—At birth or develops later in life

  9. Causes • Maternal Rubella • Meningitis • Heredity • Noise • Head trauma • Malformation of the inner ear • Impacted ear wax • Fluid in middle ear (from colds) • Punctured eardrum

  10. Prevention • Protect your ears—turn volume down to music • Early diagnosis—have your hearing tested • Avoid recreational risks—wear hearing protectors or take breaks from loud activities

  11. Tests and Diagnosis • General Screening Tests—Dr. speaks at various volumes to see how you respond • Tuning Fork Tests—Metal instrument that produce sound when struck • Audiometer Tests—Earphones are worn to hear various ranges of tones directed to one ear at a time

  12. Treatment • Removing Wax Blockage—Dr. may loosen it with oil, then flush, scoop, or suction the softened wax out • Hearing Aids—makes sounds stronger and easer to hear • Cochlear Implants—amplifies sound and directs it into ear canal; compensates for damaged or nonworking parts of the inner ear

  13. Cochlear Implants • Cochlear implants use an external microphone and speech processor that you generally wear behind your ear. A transmitter sends radiofrequency signals to a surgically implanted electronic chip, the receiver-stimulator, which stimulates the auditory nerve with electrodes that have been threaded through the cochlea.

  14. Strategies for Inclusion • Can be misdiagnosed with behavioral problems • Attention span is shorter • General education may be MOST restrictive environment • Much emphasis placed on reading

  15. Communication Tips • Gain attention • Don’t shout • Rephrase when misunderstood • Moderate pace, not slow • Use facial expressions and gestures

  16. Implication for P.E. and Sports • Learn basic signs—stop, go, freeze, line up, wait, or yes and no • Visual Timer—visual countdown for activities performed in time increments • Visual Stick—Pictures/symbols for the days activities • Use colored jerseys to distinguish teams • Use visual cues for changing stations • Provide a helmet for the necessary activities
