Audiological Research Over Six Decades

As a pioneer in the field of audiology, Dr. James Jerger has been involved in cutting-edge resource throughout the development of the field. In his new text, Audiological Research Over Six Decades, readers can experience the evolution of diagnostic audiology through his unique perspective. By detailing case studies from his own work over the years, Dr. Jerger gives his audience a chance to be a fly on the wall for major moments throughout the history of audiology.

In the first section of the book, Dr. Jerger relates case studies and other stories from his early years in the field, including his time at both Northwestern University and the Houston Speech and Hearing Center. Then, he traces his years at Baylor College of Medicine. In the final section, he discusses his time researching auditory event-related potentials at the University of Texas.

From the Foreword by Brad A. Stach, PhD

“This book is an adventure. It tells the story of the evolution of diagnostic audiology through the voice of one of its greatest contributors, Dr. James Jerger… Jerger’s lively narrative describes, in his wise and witty way, what he was thinking throughout six productive decades of game-changing audiological research. He provides us with a view, through case studies of his own work, of an unparalleled perspective, from the room where it happened."

Review

“…Audiological Research Over Six Decades provides us with a historical glimpse into how the research was performed, and its evolution, and in some cases, its return to the olden days. … Throughout the book, research is combined with anecdotal experiences that provide the reader with wonderful stories that either contributed to audiological research, or allow the reader to be just a fly on the wall, such as being in the taxi as a young Dr. Jerger shared a cab ride with Dr. von Bekesy.
The book is divided up into ten chapters, spanning 60 years. The first chapter, “The Early Years” describes a foray into “site of lesion” testing – something crucial in the 1950s – to attempt to distinguish between brainstem pathologies and those in the temporal lobe…
Subsequent chapters deal with the history and early research behind immittance testing and how Dr. Jerger’s career comes into focus in a chapter on 'Binaural hearing aids.' …
Other chapters deal with age and gender issues and, of course, auditory event-related potentials. Throughout each of the chapters, Dr. Jerger’s own musings and unexpected meetings with many of the great research pioneers of our field paint a vivid picture of audiology over the past half-century. ”
