The impact of spatial distribution of noise pollution from music recreation facilities and residents' perceptions in Chongqing municipality.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
With the rapid development of the night economy, the effects of noise pollution and the spatial differentiation characteristics of music leisure and entertainment facilities have become important issues in urban governance. Taking Chongqing city as an example, this study utilized AutoNavi POI data, noise complaint records, and field monitoring data to reveal the spatial distribution patterns and residents' perceptions of noise pollution from music facilities. The study found that: (1) Music leisure and entertainment facilities in Chongqing exhibit a "multi-core" decentralized pattern, differing from the "core solo diffusion" pattern observed in lowland cities. Due to topographic segmentation, Chongqing presents a unique "valley agglomeration-platform jumping" differentiation. The core areas (Guanyin Bridge, Jiefangbei, etc.) overlap with active night economy zones, while secondary nodes (such as university towns) show local agglomerations due to terrain constraints. (2) The distribution of music leisure and entertainment facilities is significantly correlated with noise complaint locations. The Pearson correlation coefficient peaks at a 250 m grid scale (r = 0.75), and the number of complaints increases nonlinearly when facility density exceeds 140 n/km², revealing the critical threshold effect of noise-carrying capacity in mountainous cities. (3) The innovative integration of citizen complaint data to construct a noise perception map verifies the feasibility of using public participation data for identifying noise hotspots. However, this approach is limited by the subjectivity of residents' complaint behaviour and the spatial coverage bias. The results of this study provide guidance for urban acoustic environment zoning control strategies and offer insights for mountainous cities to balance commercial vitality with acoustic environment governance.
