Willing is not enough; we must do.” —Goethe Advising the Nation. Improving Health. The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Acad- emy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engi- neers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineer- ing programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sci- ences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its con- gressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the gov- ernment, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org COMMITTEE ON NOISE-INDUCED HEARING LOSS AND TINNITUS ASSOCIATED WITH MILITARY SERVICE FROM WORLD WAR II TO THE PRESENT LARRY E.

The review of this report was overseen by Hyla Napadensky, Napadensky Energetics Inc. (retired), and Linda D. Cowan, Health Sciences Center, University of Oklahoma. Appointed by the National Research Coun- cil and Institute of Medicine, they were responsible for making certain that an independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution. Preface This report represents the collective efforts of many people over a pe- riod of approximately 15 months. First and foremost are the committee members, who devoted countless hours of volunteer service to address the committee’s charge. The numerous discussions held, both face to face and via conference calls, were thorough and, when opinions differed, were al- ways conducted with respect for divergent views. The report reflects the broad input and consensus of all committee members and is much stronger as a result. Clearly, the charge could not be addressed without a panel hav- ing sufficiently broad areas of expertise, but also a willingness to listen to sometimes differing perspectives with an open mind before moving to con- sensus. I truly appreciate not only the amount of expertise available through the committee, but the manner in which each member shared that expertise and worked together to meet our collective responsibilities. Another group central to the committee’s work included the staff mem- bers from the Institute of Medicine (IOM) and National Research Council (NRC) who supported our efforts. Lois Joellenbeck, who served as study director, and Jane Durch were the committee’s principal guides. We were ably aided as well by research assistant Kristen Gilbertson, whose contribu- tions included not only research and administrative tasks, but also partici- pating in the collection and entry of data from veterans’ medical records. Program assistant Allison Berger managed the logistics of many of the committee’s earlier meetings. Karen Kazmerzak helped initiate our research efforts during the first 3 months of the committee’s work. Susan Van Hemel, a senior program officer with the NRC, contributed advice throughout the study. ix
