  1. Hearing Impairment (H.I.) Morgan Hartwig and Ally Trudell

  2. Hearing Loss Simulation • Sound in quiet environment with normal hearing • Sound in noisy environment with normal hearing • Sound in quiet with moderate to severe hearing loss • Sound in noise with moderate to severe hearing loss • Sound in quiet with profound hearing loss • Sound in quiet with cochlear implant distortion

  3. Misconceptions (that we will correct) • When a student has a hearing aid or cochlear implant, they are “fixed” and can hear normally. • Over-enunciating words and speaking loudly makes it easier for students to understand. • Sign language and lip reading work for all adults and children with hearing loss and are the preferred methods for communication. • Hearing loss is genetic and occurs at birth or in old age.

  4. Introduction • Hearing impairment occurs when there is an inability for sounds to be transmitted through or interpreted by our brain • Hearing impairment can begin at birth (congenital) or can occur over time (acquired) • Noise-Induced Hearing Loss (NIHL): headphones, TVs, video games • Acquired loss can be sudden or progressive • Hearing impairment varies for each person and can differ in severity in each ear • Hearing loss is the most common birth anomaly (3 in 1,000) and occurs in 1 in 10 adults

  5. Types of Hearing Impairment • Sound waves travel to the ear and are interpreted by our brain • Conductive hearing loss vs. Sensorineural hearing loss or mixed hearing loss (both)

  6. Conductive Hearing Loss • Conductive hearing loss occurs when there is a problem with the ear canal, ear drum, middle ear, or ossicles • Sounds are heard much lower than they are heard by others • Can usually be fixed with surgery • Otitis media: ear infection • Ruptured ear drum • Change in air pressure

  7. Sensorineural Hearing Loss • Sensorineural hearing loss occurs when there is a problem with the cochlea or auditory nerve • Permanent hearing loss • Hearing aids and cochlear implants • Cochlear implants bypass damage and send signals straight to auditory nerve • Auditory Neuropathy Spectrum Disorder • Genetic disorders (50% of hearing loss) • Head injuries • Complications during pregnancy • Severe illness

  8. Pre-Lingual vs. Post-Lingual Hearing Loss • Pre-Lingual hearing loss can lead to delays in language, communication, and social skills • Low self-image, emotional and behavioral difficulties • ASL and lip reading • Early intervention! • Post-Lingual hearing loss does not require as much modification

  9. Signs of Hearing Loss Does your student… • Ask you to repeat yourself often or get upset at the volume of noises in the classroom? • Develop vocabulary more slowly than their peers? • Have speech that is difficult to understand or that is too loud or too soft? • Often ask for words to be repeated? • Turn on the TV/headphones too loud? • Appear inattentive at school and have trouble learning to read or perform simple mathematics?

  10. Modifications • Eye contact! • Before beginning instruction • Face the student • Speak clearly, but don’t exaggerate • Use body language • Physical contact appropriate when eye contact is not maintained • Establish cue system and routines • Emergency procedures • Parent contact and communication • Student input/feedback regularly

  11. Curricular Accommodations • Technology and Visuals • FM systems: transmitter microphone with speakers or receiver • Voice recognition software • Videos with closed captioning • Beware of “visual pollution” • Written questions and content before instruction • Repeat new material, vocab • Sensitivity to other sight, taste, smell, touch • Location of seat; low traffic areas • Background noise
