  1. DEAFNESS ….and the importance of non-verbal communication

  2. Hearing Loss • ‘Normal’ functioning ear accepts sound waves and transforms them into neural impulses that are decoded in the temporal lobes of the brain. • Breakdown in hearing may occur in one or more of the transmission processes. • Hearing loss may occur from a restriction in the range of frequencies received by the ear, intensity of the perceived sound or both. • Hearing loss can vary in severity from slight/mild to profound. Horvat et al. (2007)

  3. Causes of hearing Loss: Genetic orEnvironemntalFactOrs??? • Answer is BOTH • 1. Hereditary -50% of all hearing losses genetic. Deafness can be inherited as dominant (14%), recessive (84%) or sex-linked (2%). • 2.Prenatal – e.g. Prenatal infections or trauma • 3. Postnatal e.g. Viral infections • 4. High-decibel noise/acoustical trauma • 5. Undetermined etiology – No specific cause Horvat et al. (2007)

  5. Education Placement • Approx 5% of school-aged children have hearing loss • Most educated in regular classrooms 1/25 in Special Classes. • Placement depends on: a. Site of impairment b. Age of onset c. Extent of hearing loss. Horvat et al. (2007)

  6. Symptoms of Hearing Loss • Teachers have opportunity to observe children and can refer them for more in-depth assessment. Note the following: • Language/speech delay • Unclear speech • Volume is turned up • Does not follow direction • Does not respond • Balance /motor control Horvat et al. (2007)

  7. Planning the physical activity program • Most children will participate in regular PE classes... • Developing means of communication crucial (Stewart, 1987). • Deaf/Hard of Hearing communicate in different ways based on: • Age loss sustained • Training/Experience • Ability • Affiliation with deaf and/or hearing culture. Note: Deafness does NOT always refer to a total lack of hearing – usually some residual hearing.
