A comparative study on the audio-visual evaluation of the grand Song of the Dong soundscape

Abstract

Abstract Soundscape heritage records the cultural connotations of different ethnic groups, the destruction, and the disappearance of certain heritage makes its preservation urgent. This work aims to explore the influence of audio-visual different sensory stimuli on the subjective cognition, perceptual dimension and value evaluation of the Grand Song of the Dong soundscape heritage. We have conducted an audio-visual interaction experiment, using 2D video and high-fidelity audio systems to show typical visual elements and cultural scenes of the Grand Song of the Dong, and combined them with questionnaires to collect subjective data. The results show that the visual stimuli have no effect on the subjective evaluation of the Grand Song of the Dong soundscape, and that the different social characteristics of the participants are the main reason for the variations. The influence of audio-visual interaction on the perception of the of the Grand Song of the Dong soundscape is greater, with an enhanced perceptual dimension than the single auditory sensory, i.e., the scale dimension, indicating that visual stimuli can enhance the sensing of spatial limitation. The introduction of the visual element results in higher scores for each heritage value than the auditory element alone, indicating a positive impact on the value evaluation. The results of these studies provide a theoretical basis for the living transmission and holistic conservation of the Grand Song of the Dong and their scenes.
