In October 1975, the initial technical guide (TG) on hearing protective devices was published by the USACHPPM HCP Office. It has not been revised until now. Although many new hearing protective devices continue to become available for use by our soldiers and noise-exposed civilians, most of the original technical advice and counsel about the fitting, care and use of these devices still remains pertinent and germane. This presentation will review the overall contents of this updated TG and lead the listener through a pictorial journey of its 15 chapters and 6 appendices. Copies of the TG will be distributed for immediate reference and use to assist those who support Army Hearing Conservation.
