In order to investigate the degree of disturbance caused by sounds under the mental task being especially paid attention to the electroencephalogram (EEG), the following experiments were conducted. The EEG for 10 subjects under the mental tasks, with or without the test-sounds, were measured. After conducting the measurements, they were asked to evaluate the degree of disturbance under the mental task. In this experiment, the four patterns of 1000Hz pure tones were presented as the test sound and the simple calculation task was given as the mental task. From the results of the experiments, it was found that the patterns of the test sound had actually influence on their degree of disturbance and paying attention to the sound was also considered related to the degree of disturbance. Form these results and implications, it is tentatively suggested that when the potential of Fm θ, i.e. frontal midline theta rhythm, becomes small, the degree of disturbance becomes large. Such a factor of the degree of disturbance is considered attributed to the concentration on the mental task.
