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.
People Who are Deaf.. Profound hearing loss Very little, even with aids Restricted ability to communicate Feel part of cultural minority—the Deaf culture
Three Groups Congenitallly Deaf—present at birth Prelingually Deaf—occurs before language development Postlingually Deaf—occurs after age 2 or language development
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
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
Degree of Hearing Loss Degree of hearing loss refers to the severity of the loss.
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
Causes Maternal Rubella Meningitis Heredity Noise Head trauma Malformation of the inner ear Impacted ear wax Fluid in middle ear (from colds) Punctured eardrum
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
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
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
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.
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
Communication Tips Gain attention Don’t shout Rephrase when misunderstood Moderate pace, not slow Use facial expressions and gestures
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
