Acoustic comfort evaluation of high-speed trains in tunnels based on EEG signals
Abstract
This study focuses on the acoustic comfort evaluation of high-speed train operating in tunnels based on electroencephalogram (EEG) signals. Field tests were conducted on a specific high-speed train at various speeds and different measurement points to collect interior noise data as the acoustic samples. These acoustic samples were then used for EEG tests on individuals, to capture participants' EEG responses. Following preprocessing and denoising of the EEG signals, features such as the power of different rhythms and sample entropy were extracted. The study analyzed the correlation between EEG features and psychological acoustic annoyance, the adopted indicator of acoustic comfort, and performed time-frequency characteristic analysis to observe the changes in EEG signals in different operating environments (Open lines and tunnels).
