Towards Development of a Mobile Assessment and Differential Diagnosis of Auditory Dysfunction: Hidden Hearing Loss and Central Auditory Processing Disorders
Abstract
The purpose of this study is to develop a screening tool to identify Veterans with hearing problems that are not detected by standard clinical hearing tests. Development of an objective and simple-to-administer test of speech understanding that is sensitive to subtle impairments in the auditory system would provide VA audiologists with evidence-based guidance for assessing the communication difficulties of Veterans without significant threshold shifts who nevertheless report increased listening effort or difficultly in challenging listening situations. This will be done by comparing an individuals performance on a test called Time Compressed Digits (TCD) with their self-reported hearing difficulties, as measured by the Speech, Spatial and Qualities of Hearing Scale (SSQ-12), to determine if this test is a good reflection of hearing abilities in everyday life. Additionally, based on auditory behavioral and electrophysiological assessment, a statistical model will be developed to predict deficits in outer hair cell function, synaptic/neuronal function, central auditory processing, and working memory based on an individuals age and their performance on the TCD task.
