Preface to the Second Edition

Harry Truman was a great leader and, some would say, an effective president. However, as is clearly evident in the second edition of our three volumes Audiology: Diagnosis, Audiology: Treatment, and Audiology: Practice Management he was off target when he said, The only thing new in the world is the history you dont know. Since the publication of the first edition of our series just 7 years ago, there has been not only new information but also new technology, treatments, and trends in practice that have affected audiology in a way that has resulted in all areas of our profession growing exponentially. We now have better diagnostic procedures, more advanced technology and treatment programs, and additional practice strategies that allow audiologists to be more effective in diagnosing and treating their patients.

Whats more exciting about the growth in the field of audiology that has occurred in the past few years is that we now have an expanding and maturing educational system for graduate students who choose to spend their lives in the profession. During the preparation of the first edition of our series, the doctor of audiology degree (Au.D.) was new. Yes, in 2000 there were programs in existence, and most universities at the time were in the planning stages of upgrading their programs to the doctoral level. However, at that time it was unclear how this shift in the educational model would impact the profession. Today, according to the Audiology Foundation of America, there are 70 university programs offering the Au.D. degree, 1500 residential students currently enrolled in Au.D. programs, and more than 3725 practicing doctors of audiology. So, we have an expanded body of knowledge that is being consumed by a growing and more sophisticated constituent body of professionals who have dedicated themselves to providing the best diagnosis and treatments to those with hearing disorders using more sophisticated practice procedures. All of these trends point to growth.

A novel thought is to consider the information in these three volumes as a mathematical equation:

X = D + T + P

where D is diagnosis, T is treatment, P is practice management, and X is the sum of all of the current knowledge in the three represented areas provided by the most knowledgeable experts in their respective fields. That is what we wanted these books to be.

People dont just decide one day that because there is more information and more individuals to consume it, they will devote a couple years of their lives to putting it together in a bundle of books. The three of us jointly arrived at the decision to publish a second edition of the trilogy, as it has become known colloquially, because we felt a need to pay back to our profession a modicum of what it has given to us. We each have been very fortunate to be exposed to some of the best mentors, have been provided with tremendous support both psychologically and financially, and have been rewarded greatly in many other ways by being audiologists. We feel that we have been fortunate to practice audiology during the period of growth that the profession has experienced. We want to share those positive experiences with our readers.
