Understanding My Audiogram
One of my jobs at the library involves cataloging. The benefit of this work is getting a look at the new books before anyone else. Fortunately for me, a few months after my hearing exam, I received for cataloging Everyday Audiology: A Practical Guide for Health Care Professionals by Kazunari J. Koike. Although this book is intended for audiologists, I found the first section on audiograms very helpful.
You see when my audiologist showed me the results of my hearing tests, I didn't really understand much except to know that it wasn't good news. For anyone who doesn't know, an audiogram is a graph that shows how a person's hearing tested at different frequencies (shown along the top). The amount of hearing loss is shown in decibels (shown along the left side). The x represents the left ear and the circle is the right ear. You'll notice on mine that the left and right ears tested practically the same and as the frequencies get higher my hearing drops off.
Everyday Audiology explains what the decibel numbers mean and also what the effects are on communication for hearing loss from mild to profound. After reading the book I dug out my audiogram and marked it with what I had learned about my situation. You can see on my audiogram picture I have labeled the varying degrees of my hearing loss and also drawn on a horizontal line at the top which shows what normal hearing would look like. If you have any questions about your audiogram, check out this book. It can be requested by interlibrary loan at your local library.
