?Red light, green light?; Two minutes instead of an hour
Math technique provides better hearing test for newborns
Nov. 5,
2003 --
 |
| Researchers have devised a new hearing test that measures the auditory brainstem response 20 times faster than current methodology. |
The marvels of mathematics may open the door to a new, improved hearing test for newborns. A mathematician and a recent electrical engineering doctoral graduate from Washington University in St. Louis have devised a hearing test that measures the auditory brainstem response 20 times faster than current methodology. The technique allows for testing on small digital machines that takes just two minutes instead of the hour current methods take, and volunteers instead of medical personnel can administer it. This bodes well for mandatory hearing testing of newborns within three years.

Additional Background: Victor Wickerhauser, Ph.D., professor of mathematics, is an expert in wavelet analysis, a sophisticated kind of harmonic analysis that is integral in analyzing and compressing data — video, sound or photographic, for instance — for a wide range of applications. He and his collaborators recently have used wavelet analysis to make improvements in radiation oncology and the development of hearing tests for newborns. He has collaborated with the FBI to apply wavelets to improved fingerprinting analysis.
