The sound of Buddhist chanting characterized by both speech and music, it played an important part of traditional culture. Its unique auditory effect needs to be studied and developed. In this paper the auditory effects of the chanting sound were explored from two aspects: mood survey and physiological parameters. The experiment was designed from the perspective of subjective auditory perception. Experiments showed that the chanting sound inhibited negative emotions, enhanced sense of calm, slowed down heart rate and increased imbalance of EEG power first, then balanced it. In contrast experiments, we found that listening to traffic noise stimulated negative emotions, inhibited positive emotions and continuously enhanced imbalance of EEG power.
The chanting sound (Chinese: song du yin sheng) played an important part of daily practice of monks in temples. We collected the chanting sound of live recording, and used selected segments of the sound as experimental signals. Before the experiment, we identified emotional words through semantic surveys. The Subjective auditory perception experiment was performed to evaluate emotional words according to series category method. Experimental data was analyzed by factor extraction. Based on the factor extraction, three main emotional components: quietness, religion and drowsiness were extracted according to the characteristics of the chanting sound. This had a certain meaning for emotion recognition, annotation and music recommendation of this kind of sound.
