This report examines the results of experiments on how noise influences the quality and quantity (and time) of mental work. The experiments consisted of changing a-weighted sound pressuer level (background noise 60, 70, 80, 90dB) during mental work, which consisted of operation activities (addition and subtraction), stamping activity with judgment, and "AMEFURI" erasion. The empirical results are described herein.(1) Operation activity (addition and subtraction): The error rates and uncompleted work increased when the level of noise increased.(2) Stamping activity: The stamping error rate and the mean value of time required increased when noise increased.(3) "AMEFURI" erasion: No influence was noticed.The above experimental results clarify the following matters. Noise exerts an influence on operation and stamping activities with judgment. On the other hand, noise does not exert an influence on "AMEFURI" erasion. The difference originates in whether or not the auditory sense exists when work is executed.
