Visualizing the Knowledge Domain in Urban Soundscape: A Scientometric Analysis Based on CiteSpace

Area of Science:

• Environmental Science
• Urban Planning
• Acoustics

Background:

• The field of urban soundscape research is rapidly expanding.
• A systematic analysis is needed to understand current research themes and knowledge structures.
• Understanding urban soundscapes is crucial for improving city living environments.

Purpose of the Study:

• To identify main research themes and knowledge structures in urban soundscape studies.
• To analyze the evolution of research hotspots and methodologies.
• To provide insights for urban soundscape research, planning, and design.

Main Methods:

• Information visualization analysis using CiteSpace software.
• Analysis of high-quality literature from the Web of Science (WoS) database (1976–2021).
• Identification of research themes, methods, and objects.

Main Results:

• Key research hotspots include noise, perception, and quality, with a focus on theory and methodology.
• The Perceptual Restorative Soundscape Scale is emerging as a primary research method.
• Research predominantly focuses on outdoor urban environments (parks, attractions, historical blocks) and associated influences and preferences.

Conclusions:

• The study maps the intellectual landscape of urban soundscape research.
• Future soundscape perception models are expected to evolve with advancements in sound technology.
• Findings offer valuable references for urban soundscape research, planning, and design practices.
