Effects of intermittent noise on human target detection.
Hum Factors 1969 Jun; 11(3):245-250
The effects of intermittent noise on target detection performance specifically, were examined to test whether the effects of noise presented at a 70 percent on-off, neutral ratio are independent of the noise intensity level. Four levels of noise were used: no noise, and 80, 90, and 100 decibels, with 24 male subjects. Both response error and response latency were recorded. The results revealed that detection time was not significantly affected by the noise level. The total number of errors recorded for each noise condition showed that, in general, as intensity level increased, the total number of errors decreased. These findings are related to the concept of flexibility of attention. (Grant No. T01-OH-00002)
