Cochlear Implants:


  • Approximately 28,000,000 in the U.S. that have hearing problems
  • Approximately 1 in 1,000 children are born profoundly deaf


  • Hearing is tested in the hospitals after birth in 2 different ways
    • 1)Brainstem Auditory Response
    • 2) Measure oto acoustic emissions
  • Parents should be concerned if:
    • Child will not babble or make sounds
    • Child does not respond to loud noises

Benefits of Receiving Implant During Critical Period:

  • Younger the child receives the implant, the faster they are capable of learning to use the device and perform better

Receiving Implant After the Critical Period:

  • May always have language limitations
  • Frequently occurs with deaf children born to hearing families who do not sign or do not detect the hearing loss early on
  • A pre-linguistically deaf adult who receives a cochlear implant may always have limited language comprehension, including difficulty with reading

Deaf Children in Deaf Families who Receieve the Implant:

  • Have very little exposure to spoken language, although they are fluent in ASL
  • May be little or no spoken English in the household
  • To learn to speak, the child will need extensive language training outside of their home
  • Then entire family must commit to this process for the best results
