The primary purpose of the book is to provide a basic understanding of hearing disorders, characteristics of hearing loss, and audiometric configurations related to disorders. The audiometric data is only part of the whole evaluation; however, it assists the provider to select the subsequent appropriate test to obtain a diagnosis for the patient (i.e. MRI, CT, and labs). In some cases, the etiology may never be known. With accurate audiometric interpretation the provider can often quantify the extent of the ear problem. Remember that the most important data you have is a thorough patient history of the hearing loss. About the Author Dr. Robinson Cummings has worked as an Audiologist since 1985.
