Abstract:

A laboratory evaluation was conducted of the comparative intelligibility of standardized speech materials MRT processed through representative Air Force communication systems in the presence of various levels of aircraft cockpit noise. The results indicated that as the level of noise was increased the intelligibility of the speech materials was systematically decreased. Although both radio systems tested were affected, the relative magnitude of the effect varied for the two systems from one noise level to the other. Author
