| Resumen |
Arithmetic tasks were performed in combination with work on a bicycle ergonometer and white noise. The best performance was obtained: with no work + noise of 70 or 85dB(AI); work at 15W + noise of 55 or 70dB(AI); work at 30W + noise of 55dB(AI). Physiological reactions taken into account were cardiac cycle duration, respiratory cycle duration, cardiac rate, respiratory rate, and epinephrin and norepinephrin excretion. In concentrated mental work noise should not exceed 55dB(AI); for moderate mental concentration it should be 70-85dB(AI) without muscular exertion, 55-70dB(AI) with light exertion, and 55dB(AI) with moderate exertion. |
