This study examined the effects of exposure to intermittent jet aircraft noise (70 dBA or 95
dBA maximum intensity) and knowledge of results concerning signal detections (hit-KR) on …

Effects of environmental variables on performance may be mediated by individual stress
states. In this study the effects of jet-aircraft engine noise and signal salience on vigilance …

Knowledge of the effect of noise on performance is limited and is generally inconclusive.
Examination of previous research indicated the need for a systematic and concurrent …

Two experiments are reported that examined the influence of variation in task demand on
performance and workload. The first experiment considered how the manipulation of prior …

Abstract SIMULTANEOUS TASKS WERE USED TO TEST THE HYPOTHESIS THAT THE
DELETERIOUS EFFECT OF NOISE ON PERFORMANCE VARIES AS A FUNCTION OF …

HE Boeing Airplane Company is now engaged in a major noise-reduction program. As a
part of that program, the Acoustics Group of the Transport Division began a study of the …

Previous research with the NASA Task Load Index (TLX) and the Subjective Workload
Assessment Technique (SWAT) has demonstrated their sensitivity to variations in workload …

The literature on the effects of noise on monitoring performance shows a disappointing lack
of consistency in results. The hypothesis of the present study was that task classification in …

A methodology for the quantitative evaluation of observed workload was proposed. The
model was designed to provide point estimations of observed workload at any time during …
