Abstract

A soundscape is a sound environment of the awareness of auditory perception and social or cultural understandings. Based on a soundscape investigation in 2019 in the historical and ethnic village of Dong Nationality in Zhaoxing County, Guizhou Province of China, a case study on the soundscape analysis with the acoustical sound pressure level and an impressive sound event or soundmark is introduced in this paper. Furthermore, in order to determine the subjective soundscape experience and its influence by the length of background music listening, the independent variable “Length of Listening” and six adjective pairs, such as “Monotonous” to “Rich”, “Clamorous” to “Quiet”, “Stressing” to “Relaxing”, “Boring” to “Vivid”, “Noisy” to “Musical” and “Disliked” to “Preferable” are chosen to obtain a curve-fit, which shows that the length of the music listening background has a higher correlation to the subjective experience, and no sufficient attention has been paid to the context of the traditional soundscape preservation, ethnic music and quiet and soft ambient sounds.

Highlights

  • Based on 37 typical binaural-recorded samples and the questionnaire on site in the historical and ethnic village of Dong Nationality in Zhaoxing County of Guizhou Province of China in 2019, a case study on the soundscape analysis with the acoustical sound pressure level, curve-fit and an impressive sound event or soundmark is introduced in this paper

  • In order to analyze the soundscape features of Keynote, Sound Signal, and Soundmark suggested by Schafer [15], with all the samples played in headphones, two listening sessions were carried out in a lab for 5 experts to extract the three features and give some comments on the tourist flow, tourist behavior, tourism routing, the form of business and the aspects of ethnomusicology (Table 2), according to following guidelines

  • According to results and discussions, for which kind of keynote, sound signal, soundmark to preserve or restore, the traditional music and dancing could be the most important soundmark with keynotes of natural sounds, local dialects and slight tourists or bossiness noise when the most important sound signal—drum beat is restored to work in its traditional ways

Summary

Introduction

A soundscape, as suggested by Schafer, is a sound environment of the awareness of auditory perception and social or cultural understandings with the three features of keynote, sound signal and soundmark [1], or as defined by ISO, an “acoustic environment as perceived or experienced and/or understood by a person or people, in context” [2]. Sound sources, acoustic environment and its subjective evaluation, individual behaviors, social and demographical characteristics are the factors that influence soundscapes in historical areas [10]. Based on 37 typical binaural-recorded samples and the questionnaire on site in the historical and ethnic village of Dong Nationality in Zhaoxing County of Guizhou Province of China in 2019, a case study on the soundscape analysis with the acoustical sound pressure level, curve-fit and an impressive sound event or soundmark is introduced in this paper. The aim of this case study is to determine which kind of keynote, so soundmark to preserve or restore, the subjective semantic soundscape experie influence by the three features and the length of background music listening.
