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.
