Week-long continuous noise levels measured by an IoT-based device - EcoDecibel, in Sanzhi District, Taiwan, Aug 12 2021 - Aug 18 2021.

Noise pollution is a growing concern in urban and rural environments, impacting public health and quality of life. We conducted a study to check the validation of an IoT based, low cost, noise sensor - EcoDecibel as compared to traditional Class 1 and Class 2 noise meters in indoor as well as outdoor environments. Data was collected continuously over a seven-day period at various sites, including arterial roadways, county highways, and environmental areas. The primary objective was to evaluate the performance of the EcoDecibel device in comparison to the gold standard noise meters which was conducted in different settings in indoor and outdoor environments and then the EcoDecibel device was set up in field to analyse the real world noise measurements.Despite its lower cost, the EcoDecibel device demonstrated a high degree of accuracy with an R2 value of 0.9 when compared to the standard devices. This dataset provides valuable insights into noise pollution levels across different environments and highlights the potential of low-cost noise measurement devices for widespread monitoring and research. The metadata accompanying this dataset includes detailed information on the experimental setup, data collection methods, and analysis procedures. The dataset is openly available for further research and validation, promoting transparency and reproducibility in environmental noise studies.
