Need for AUDIOscreener



Newborn Nursery: 1 per 1000
NICU: 3 to 4 / 1000
Average Age of Detection of HI
in America: 18 months to 36
months (U.S. Dept. of Health
and Human Services, 1990)
Hearing Impairment: Areas Affected




Speech and Language
Social and Educational
Emotional and Vocational
Loss of Income to Society: $2.5
billion/Year
Solution
Develop a Portable Screening Device:
 inexpensive
 accurate
 simple
 user-friendly
How does it work?

Otoacoustic Emissions
Echoes/reflections from the inner ear
in response to brief sounds such as
clicks or tones

Auditory Brainstem Response
Electrical responses from the hearing
nerve and the brainstem to brief
sounds such as clicks or tones
Success Story


Successful FUR
External funding for SIUE
researchers
Clinical trials are underway at
SIUE to evaluate the overall
effectiveness of the device
FDA approved
Device should reach
marketplace within next 3
months (Elvir ????)
