| 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.
