| Abstract |
This paper attempts to confirm the relaxation effects of various ASMR sounds. For the experiment, twelve ASMR sound auditory stimuli were presented to thirteen male subjects (mean age 29.30 ± 2.05). EEG relative power spectral measurements and subjective relaxation questionnaires were used to assess relaxation levels. As results of EEG frequency band analysis, the theta band was dominant in 'silence' and 'firewood sound'. and the theta band and the alpha band were dominant away other ASMR sounds. The EEG response was categorize into three: 1) the sound with reduced theta band and decreased alpha and beta bands with significant differences compared to silence, 2) the sound with reduced Theta band and increased alpha band with significant differences compared to silence, and 3) the sound with no significant differences in the EEG band versus silence. As a result of subjective relaxation analysis[13], 'Silent', 'firewood sound', and 'rain sound' were observed to tend to relax. And the remaining 10 ASMR sounds were reported as a medium level of relaxation and arousal. In conclusion, some ASMR sounds were found to have sleep induction. The study provided data to ASMR users and producers by using for quantitative approach. |
