520 ‡aThis report compares performance under the combined stress of noise and fatigue with that of fatigue alone. A complex mental counting test which involves mental work of a rather high order was the source of the performance measure. Although statistically significant differences between performance in noise and in quiet were found, these were not straightforward, and no simple relationship of the performance decrements and specific abilities could be established. It is therefore impossible to relate abilities involved in performance on the complex counting test to changes in performance under noise stress. Some indication was found of a direct relationship between susceptibility of individual subjects to auditory fatigue during a specific work period in noise and their ability to maintain performance in noise.
