About three out of every 1,000 babies in the U.S. are born with hearing loss. Left untreated, this can have devastating effects on speech and language development and, in turn, on academic performance later in life. Research on owls may help improve early diagnosis and intervention options.<\/p>\n\n\n\n

Diagnosing Infant Hearing Loss\"\"<\/h2>\n\n\n\n

The Early Hearing Detection and Intervention (EHDI) program, implemented in all 50 states, aims to screen every infant for hearing loss<\/a> by one month of age, diagnose hearing loss by three months of age and provide early intervention or treatment by six months of age.<\/p>\n\n\n\n

While this program has helped countless children across the U.S. develop their speech-language skills alongside their normal-hearing peers, the system isn\u2019t perfect, largely because traditional hearing tests aren\u2019t designed for babies.<\/p>\n\n\n\n

According to pediatric audiologist Kristy Knight<\/u><\/a>, \u201cOne of the things that we really struggle [with] young children is knowing, can they recognize the difference between sounds like \u2018else\u2019 versus \u2018elf\u2019, for example? Our regular hearing tests don\u2019t tell us that. We have to wait till the child has some amount of language development to really measure that clinically.\u201d<\/p>\n\n\n\n

How Research on Owls Can Help<\/h2>\n\n\n\n

About 20 years ago, Avinash Bala, a neuroscientist at the University of Oregon, worked on a research project aiming to condition barn owls to respond to various sounds and study how they hear in order to better understand how humans process sound. While the conditioning effort was ineffective, Bala made an important discovery: owls\u2019 eyes dilate in response to new sound stimuli.<\/p>\n\n\n\n

Bala is still unsure why this phenomenon occurs. He hypothesizes it may be a biproduct of how organisms have evolved to orient themselves within the world, or that it allows the animals to hone in on a specific object that catches their attention, like a predator or prey.<\/p>\n\n\n\n

He had a realization much more important than why<\/em> this response occurs, however: \u201cWhat I realized was that we could also use this in people who are unable to respond for one reason or another. And the biggest such group of people is infants, because babies can\u2019t tell us what they\u2019re thinking.\u201d<\/p>\n\n\n\n

Looking to the Future<\/h2>\n\n\n\n

Bala and Knight, who works at OHSU Doernbecher Children\u2019s Hospital, are partnering together to develop pupil-response testing that will provide audiologists with another tool for diagnosing infant hearing loss.<\/p>\n\n\n\n

\u201cWhat we\u2019re proposing is that if we have a test that doesn\u2019t require expertise, any audiologists can administrate,\u201d Bala said. \u201cWhat it involves essentially is putting a baby in his mother\u2019s lap or in a high chair playing sounds\u2026 and at the end of 15 minutes, the computer just comes that gives you up yes or no answer.\u201d<\/p>\n\n\n\n

The team hopes to produce a prototype of the test sometime this fall.<\/p>\n\n\n\n
