Abstract

Urban educational environments are increasingly burdened by elevated ambient noise levels, which compromise cognitive performance and well‐being of students (WHO, 2018; Stansfeld & Clark, 2015) [18]. This study presents a spatial analysis of noise pollution across five strategic locations within a university campus in Kanpur City, employing a Class 1 sound level meter over a continuous four‐week period in February–March 2025. Key metrics—equivalent continuous sound level (Lₑq), percentile levels (L₁₀, L₉₀), and peak (Lmax) and background (Lmin) values—were recorded following ISO 1996-2 (2017) [6] guidelines. GIS‐based noise contour mapping revealed that 30 % of the campus area exceeds 70 dB(A) daytime, with the main gate zone registering the highest mean Lₑq of 74.8 dB(A), significantly above the CPCB limit of 55 dB(A) for educational zones (CPCB, 2000) [2]. ANOVA and Tukey’s HSD tests confirmed highly significant spatial differences (p < 0.001) between highway‐adjacent sites and interior zones. Vehicular traffic accounted for approximately 60 % of noise incidents, with construction and HVAC systems contributing the remainder. Based on these findings, we propose targeted interventions—including 3–5 m acoustic barriers (Johnson & Brown, 2017) [9], vegetative buffer belts (Zhang et al., 2020) [19], and schedule optimization of noisy activities—to achieve up to 12 dB(A) attenuation. This research provides an evidence‐based framework for campus noise management and informs urban planning policies to safeguard learning environments in rapidly urbanizing contexts.
