Research on Differences in Urban Sound Perception and the Equity of Public Space Experiences

Abstract

The fairness of acoustic landscape experiences in urban public spaces has become a cutting-edge topic in environmental justice research. Starting from the theoretical framework of acoustic landscape equity, this paper comprehensively examines the mechanisms underlying disparities in urban sound perception and their impact on equitable spatial experiences. The study identifies four key dimensions of acoustic landscape equity: equitable spatial distribution, equitable noise regulation, equitable sound perception, and equitable acoustic health outcomes, which collectively form a logical chain spanning resource allocation to health consequences. Urban sound perception varies significantly due to physical environmental factors and social stratification, with marked differences in access to acoustic resources between high-income and low-income areas. Achieving acoustic landscape equity requires coordinated efforts in physical space governance, social participation mechanisms, and digital technology empowerment. Integrating acoustic landscape equity into urban public space governance constitutes a fundamental pathway toward building inclusive cities.
