Research Abstract |
This study examines the results of experiments on how noise influences the quantity and quality of mental work. The experiments consisted of changing noise classification (steady and intermittent noise), noise spectrum (63 - 125, 250 - 500, 1 - 2k, 4 - 8kHz) and a-weighted sound pressure level (65, 75, 85, 95dB) during mental work, which consisted of stamping activity with judgment. The results can be summarized as follows. 1. The quantity and quality of mental work decreased when the level of noise increased. 2. The quantity of mental work decreased when the noise spectrum 1 - 2kHz, but the quality of mental work was not influenced very much of the noise spectrum. 3. The quantity and quality of mental work were independent of the noise classification. 4. Noise exerts an influence on stamping activities with judgment. 5. The mental fatigue of the operator increased as the noise levels were increased. 6. Farm work noise exerts an influence on operating in farm works with judgment.
