Auditory Practice Necessary to Influence Neural Structure (Mastery)

  • (Dehaene, 2009): 20,000 hours of listening as basis for reading

  • (Gladwell, 2008): 10,000 hour rule key to success

  • (Hart & Risley, 1995): 30 million word gap study

  • (Pittman, 2008): Children with HL require 3X the exposure to learn each new word and concepts due to reduced acoustic bandwidth caused by HL


30 Million Word Gap Study(Hart & Risely 1995)


NPR: Sean Forbes: Deaf but not Quiet


32 million Americans have hearing loss.Can you identify each of the celebrities?


You Are Not Alone!

  • One in ten Americans has a hearing loss


OSHA

  • 5-10 million Americans are at risk for NIHL exposure to sounds above 85 dBA in the workplace

  • 48 million Americans engage in shooting sports, the most common cause of non-occupational NIHL


Question

  • How many babies are born annually in the U.S.?

  • A. 3 million

  • B. 4 million

  • C. 5 million

  • D. 6 million

  • E. Heaven knows?


Quick Facts

  • 4 ________ babies born in U.S. annually

    • 3-5/_____ babies born with hearing loss

    • 1 in 1,000 U. S. newborns (or 33 babies every day) are born profoundly deaf

    • 2-3 out of 1,000 babies born with partial hearing loss, making hearing loss the number one birth defect in America.

  • _____ million Americans have hearing loss

  • _____ most chronic condition for the elderly


Hearing Identification in (U.S.)

  • About 95% of newborns screened for HL

  • 91% of referred infants returned for follow-upevaluation.

  • 39% fit with HA by 6 mo.

  • 61% fit late or lost to follow-up.

    • Unilateral hearingloss and late diagnosis were statistically significant (p <.0001) predictors for late fitting and loss to follow-up. 

      (Spivak 2009)


Auditory Development

#1 Factor: Age at fitting of amplification (for children with congenital hearing loss) in predicting every outcome in auditory development
