Electrocochleography As A Means To Assess Auditory Function Following Noise Exposure
Andrew Stuart1 & Alyson Butler Lake2 1Department of Communication Sciences & Disorders, East Carolina University, Greenville, NC 2Blue Ridge Ear, Nose, Throat & Plastic Surgery, Lynchburg, VA Electrocochleography (ECochG) has been employed to assess stimulus-related cochlear potentials and the compound action potential (AP) of the auditory nerve. The cochlear potentials include the cochlear microphonic (CM)…

by Tony L. Sahley, Ph.D., CCC-A Acoustic overstimulation (AOS) is defined as an over-exposure to stressfully loud sounds. AOS often results in symptoms that include a chronic reduction in hearing sensitivity, referred to as a sensorineural hearing loss (SNHL). AOS is the principal cause of acquired SNHL and is second only to SNHL that is…
Read MorePathways in the Brain Germane to Audiologists: A Brief Commentary
by Frank E. Musiek, Ph.D. Most audiologists are familiar with at least two major pathways in the brain. One is the ascending (and descending) auditory brainstem pathway and the other is the ascending (and descending) vestibular brainstem pathway. In the cerebrum there are also pathways of importance to audiology. These include, in our view,…
