The present study compares the accuracy in short-term noise monitoring strategies in comparison to the long-term monitoring strategies. The difference in short-term strategies from the annual average yearly sound levels is quantified as an error. The study extends the previous work reported exclusively for silence, industrial, commercial and residential zones in Indian scenario. The study re-affirms that random two months’ strategy is the Best Practicable and Economic Option (BPEO), whereby an error of ± 2 dB is observed with a probability of 95% approximately. Adopting long-term noise monitoring strategy in larger parts of Indian cities is cumbersome and expensive process. Thus adoption of random two months’ strategy adopted exclusively for silence, industrial, commercial and residential zones can be a practicable and economical option for noise mapping of larger parts of Indian cities.

短期噪声监测策略与长期噪声监测策略相比的准确性

本研究比较了短期噪声监测策略与长期监测策略的准确性。短期策略与年平均声级的差异被量化为误差。该研究扩展了之前专门针对印度情景中的沉默、工业、商业和住宅区报告的工作。该研究再次确认随机两个月的策略是最佳可行和经济选项 (BPEO)，其中观察到 ± 2 dB 的误差的概率约为 95%。在印度城市的大部分地区采用长期噪声监测策略是一个繁琐且昂贵的过程。因此采用随机两个月的策略，专门用于沉默、工业、
