Effects of Electromagnetic Field and Noise on Resting Electroencephalogram of Health Subjects

Not Applicable

Completed

• Conditions: Electroencephalography; Noise Exposure; Electromagnetic
• Interventions: Other: noise expose; Other: RF expose

• Registration Number: NCT05184686
• Lead Sponsor: Xijing Hospital

Brief Summary

With the development of science and technology, there are more and more electromagnetic and noise factors in the working and living environment. These two factors often exist together, and their impact on people may interact. Scalp EEG is a classic nerve detection technology, which can reflect the functional state of the brain in a non-invasive and real-time manner. This project intends to use EEG technology to study the effects of electromagnetism and noise on human brain function.
