A number of studies in the field of mental workload have been able to measure, on a subjective scale, the time load, mental effort and psychological stress associated with performing a particular task. Other studies have concentrated on the physiological measures of mental workload, including eye blink, brain waves and heart rate. The objective of this study was to observe correlations among the physiological parameters and the subjective factors from subjects performing a dual performance task in ambient and high noise level environment. The application is in the field of assessment of human performance and workload in advanced, high performance aircraft cockpits. Dual task methodology consisted of a primary tracking display and a secondary task of monitoring a Radar Homing and Warning Display (RHAW). Subjects were trained on the dual task and their performance scores were correlated to reaction times, subjective workload scores (SWAT) and changes in physiological parameters. The effect of noise served as the biodynamic stressor. Pink noise consisted of two levels, 90 and 100 dBA. Physiological parameters monitored included EKG, EEG, arm muscle EMG, eye blink, and blood pressure.
