Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first report on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform less well with binaural than monaural stimulation. Binaural interference is relevant to every audiologist because it may impact the successful use of binaural hearing aids. This exciting new book, written by two highly respected audiologists, first traces the history of research into binaural interference, 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 four illustrative cases. Next, a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference is outlined. This is followed by suggestions on how to improve techniques for evaluation of the binaural advantage in general, and improved 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, research on binaural interference only recently has begun to flourish. Adapting audiological clinical practice to identify, assess, and manage individuals with binaural interference is not yet widespread. The authors hope that the book will provide impetus for pursuing further research and encouraging audiologists to explore the possibility of binaural interference when patient complaints suggest it. The book is intended for practicing clinical audiologists, audiology students, and anyone interested in pursuing serious research on this interesting phenomenon.
