Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study is to develop an optimized hearing testing method using otoacoustic emissions, that can be used to efficiently assess peripheral neural function (including retrocochlear disorders) using the medial olivocochlear reflex (MOCR). Measuring neural function via the MOCR. This reflex has been shown to be abnormal in patients with neural disorders. The focus of this project will be the development of a screening method that incorporates OAE screening and measurement of the MOCR in the same test procedure. The target population in the proposed research is infants, particularly those in environments where auditory brainstem response (ABR) screening is not performed routinely. Addition of the MOCR to screening where ABR is not performed will address the shortcoming of OAE screening which misses neural forms of hearing loss.
