Valid and realistic criteria are needed for identifying and determining potentially hazardous noise encountered during ground and airborne aerospace operations. A set of criteria proposed by a working group on hearing, bioacoustics, and biomechanics, has been modified for easier interpretation and use in assessing auditory risk. An auditory risk calculator has been devised to simplify the task of assessing wide-band and narrow-band noise exposures. In addition, a simple chart has been prepared for use in evaluating intermittent noises. Examples of noise exposures encountered in aerospace operations are illustrated and applications of the three basic types of auditory risk criteria are demonstrated. Desirable and undesirable features of older and newer criteria are discussed. Author
