Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first published study on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform more poorly with two hearing aids than with one and/or more poorly with binaural than monaural stimulation on electrophysiologic as well as behavioral measures. Binaural interference is relevant to every audiologist because it impacts the successful use of binaural hearing aids and may explain communicative difficulty in noise or other challenging listening situations in persons with normal-hearing sensitivity as well as persons with hearing loss.

This exciting new book written by two highly respected audiologists first traces the history of its study by researchers, then reviews the evidence, both direct and indirect, supporting its reality. This is followed by a discussion of the possible causes of the phenomenon and in-depth analysis of illustrative cases. The authors outline a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference. Suggestions are furnished on improved techniques for evaluation of the binaural advantage in general and on sensitized detection of the disorder in particular. The book ends with recommendations for future directions.

Given the adverse impact of binaural interference on auditory function and its occurrence in a significant subset of the population with hearing loss, as well as in some individuals with normal-hearing sensitivity, research on binaural interference only recently has begun to flourish, and adaptation of audiologic clinical practice to identify, assess, and manage individuals with binaural interference has yet to become widespread. The authors intend for the book to provide impetus for pursuing further research and to encourage audiologists to explore the possibility of binaural interference when patient complaints suggest it and when performing audiologic evaluations.

The book is intended for practicing clinical audiologists, audiology students, and hearing scientists.

Reviews

"As the editor in chief of ''Canadian Audiologist'' it is my responsibility to select reviewers for new publications. Typically this can be like pulling teeth but for Binaural Interference: A Guide for Audiologists there was a deluge of volunteer reviewers. I first thought of playing King Solomon who threatened to divide a baby in biblical times by cutting up the book and sending a bit to each of the reviewers, but I decided to keep the book to myself to review. Binaural interference has been described in the literature as early as 1939 and refers to the fact that, in some individuals, speech entering one ear interferes with the same speech coming into the other ear. This has ramifications for hearing aids, where two hearing aids may not result in a binaural fitting. This short 124-page book has 7 chapters, each of which is concise and well-written. In some other hands this book undoubtedly would have been needlessly longer, but Doctors Jerger and Silverman get directly to the point. Having said this, the book is very easy to read and the literature review proceeds as a very logical story line. Each chapter ends with a summary. Chapters 1-3 provide a history of the discovery that perhaps the brain cannot always properly synthesize the information from the two ears. There is a clear discussion of the direct and the indirect evidence of binaural interference with a review of the possible causes. This may in part be related to cochlear sensory asymmetries or asymmetrical function in the neural processing between the two ears, including the role of the corpus callosum. Chapter 4 provides some illustrative examples of binaural interference for people with age-related sensori-neural hearing loss and with neural involvement. Chapter 5 deals with the clinical evaluation of binaural interference and chapter 6 deals with future directions touching on some possible methods to begin assessing this. The final chapter (7) has the title of Lessons Learned. It provides a clinically relevant summary of what the audiologist needs to know to assess, and be on the look-out, for the possibility of binaural interference with their clients. This book, which I highly recommend, dovetails nicely with another book by Dr. Jerger- James Jerger: A Life in Audiology (Plural Publishing, Inc.). This is a delightful book about Dr. Jerger's professional life where there are frequent hints about his long-standing interest in binaural interference."
Marshall Chasin, AuD, Editor-in-Chief, in Canadian Audiologist (Vol. 5, Issue 3, May 2018)

"This is a really thought-provoking book that forces the reader to contemplate beyond the norms on so many levels. Unlike typical Jerger books, this is a very light read and I managed to finish all 100+ pages in a straight 3-ish hours on a train journey as I could not put it down after starting it. It was a bit like a crime thriller, trying to find the true nature of the culprit, which here is binaural interference. Binaural interference is guilty of making binaural fittings worse than monoaural. So, the concept here is that some of your clients who have been given two hearing instruments may actually benefit more when they only use one. Sounds bizarre at the outset but there is plenty of support provided in the form of new and old evidence for this argument in the book... There are several beautiful illustrations in the book. I particularly liked the flawless flow of information that keeps the reader engaged in a virtual conversation and curious about what is to come next."
Jay Jindal, AuD, FSHAA, in the British Society of Hearing Aid Audiologists' BSHAA People (October 2018)

"This book details what binaural interference is, it looks at the basic principles of this topic and follows the research over the years that has gone into investigating what causes binaural interference. It makes for an interesting read, covering a topic that, within audiology, is a very interesting phenomenon. It is very easy to follow and read, and it breaks down each study in detail looking at the pros and cons while discussing the relevance of each study."
—Rebecca Day, in ENT & Audiology News (July 2019)

James Jerger

James Jerger, PhD, a native of Milwaukee, Wisconsin, received his PhD in audiology from Northwestern University (NU) in 1954. He remained on the NU faculty until 1961 and then moved to Gallaudet College in Washington, DC, for a brief period as Research Professor of Audiology. From 1962 to 1968, he served as Director of Research at the Houston Speech and Hearing Center and then moved to Houston's Baylor College of Medicine, where he remained for the next 29 years as Professor of Audiology in the Department of Otolaryngology and Communicative Sciences and as Chief of the Audiology and Speech Pathology Services of the Methodist Hospital. In 1997, Jerger sought, but failed to achieve, semi-retirement in the School of Behavioral and Brain Sciences of the University of Texas at Dallas. Here he continues to mentor doctoral candidates in audiology as Distinguished Scholar-in-Residence.
