The Correlation between the Emotional Reaction by Different Personalities and the Cerebral Cortex Activation in the Environmental Low-Frequency Noise

The noise control regulations of the Environmental Protection Administration (EPA) have not considered the effect by the low-frequency noise until 1995. However, EPA has received the complaints of more than 30% which were about the low-frequency noise in every year before 1995. The level of the low frequency noise was measured and controlled by the regulations, but people still felt so noisy and annoy that people petitioned again. The low frequency noise of the frequency range between 20 Hz to 200 Hz was defined in the noise control regulations revised on Jan. 31st, 1995. Note that the level was controlled under 40 dB(A). It is not enough direct evidence for the demonstrating of the frequency range and the level based on scientific research or the related literature about the effect of low-frequency noise to the citizen’s health in the past. This study will explore the correlation between the low-frequency noise on the human emotional impact and activation at the cerebral cortex based on the scientific research in acoustics, cognitive neuroscience, personality, and environmental policies. To provide the evidence for the effect of low-frequency noise to the citizen with different character will result in negative emotions. The stress generated by the negative emotion will affect the physiological system and psychological condition. Hence, we hope that we can find the great cut-off point for the frequency range and the controlled level of low-frequency noise. Furthermore, we expect that the result will be the reference to EPA for making the strategies and policies in environmental protection.
