Abstract:

The purpose of this investigation was to assess mans performance in a work situation wherein 90 dB continuous and periodic 96 dB intermittent noise were separately presented as environmental or work-situation stressors. The present study employed a synthetic-work approach in which several tasks were combined into a multiple-task performance battery MTPB consisting of six tasks selected to test both individual- and small-group crew performance. The results, showed that the mean percentage of baseline performance was enhanced by a periodic 96 dB intermittent noise. On the other hand, since continuous noise may be considered as containing fewer stimulus elements than intermittent noise, it was expected that general performance during continuous noise would be less than during intermittent noise.
