Scholars studying the processes that lead to significant alterations in public policies have identified two major sources of change: policy-oriented conflict and policy-oriented learning. Many investigations of specific cases of consequential policy

Beginning at least with Brown in 1977, scholars have argued that environmental concerns be incorporated into the security calculations of nation-states. In recent years, the "environmental security" thesis has been used to justify rhetorical and inst

The identification of characteristics of noise-susceptible (S) or noise-resistant (R) individuals is necessary for the development of noise-susceptibility risk profiles. Fifty-six naval aviators, categorized as having either incurred a hearing loss,

The present invention provides means of enhancing the acoustic attenuation and vibration damping of a material by (1) embedding a plurality of small particles of either a high characteristic acoustic impedance or a low characteristic acoustic impedan

The ability to receive radiocommunications in a noise field while wearing double hearing protection (i.e., circumaural muffs and ear plugs) was assessed under simulated aircraft noise conditions. A version of the modified rhyme test [i.e., the tri‐

A microcomputer‐based battery of tests has been developed to assess the performance of aviators on auditory tasks deemed important in the operation of aircraft. Included in the test battery are measures of hearing threshold levels, speech perceptio

The frequency discriminability of a 70-dB SPL, 20-msec test tone followed 5 msec later by an equally intense 500-msec, 800-Hz interference tone was studied in a single-interval procedure for one diotic condition and three dichotic conditions. The tes

The frequency discrimination of a 20-msec test tone was measured for the same subjects in four psychophysical paradigms: a single-interval procedure, a two-alternative forced-choice procedure, a same-different procedure, and a method-of-adjustment pr
