Official title
Otoacoustic Emission Suppression in Clinical Populations
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The focus of this project is on a physiologic auditory response called the Medial Olivocochlear Reflex (MOCR) that assesses peripheral neural function. While neural hearing loss is a significant auditory disorder in patients of all ages, more than 50% of newborn infants are screened with a technology that is not sensitive to abnormalities in neural function. The development of a time-efficient and sensitive test system to assess the MOCR will provide significant benefit to infants and patients of all ages with neural deficits who would otherwise go undetected.
