| Sumario: | This study compared the effects of noise under active task involvement as opposed to passive exposure. Eighty subjects were assigned to one of four conditions, representing 2 × 2 combinations of task versus no task, and noise versus quiet. Performance on a dial-monitoring task was unaffected by noise. Ratings of interest and tenseness were significantly higher under the task condition; tenseness was also higher under noise. On a posttest of resistance to frustration, both noise groups, regardless of task condition, showed a smaller degree of persistence on insoluble puzzles than the no-noise groups. These results suggest that aftereffects of noise are not dependent on the power of noise to disrupt task performance.
