The authors have previously proposed adoption of the CHABA Working Group 46 criterion for steady-state noises to assess degrees of auditory risk associated with aerospace operations. In this report, the salient features of various damage risk criteria are reviewed and primary and secondary compromises are discussed. A simple criterion using A-weighted sound levels is proposed for broad-band and narrow-band steady-state and intermittent noise and for impact noises. The criteria contained in this report provide guidance needed to identify potentially hazardous exposures encountered in aerospace operations. Author
