摘要：

Railway noise, stemming from various sources such as wheel/rail interactions, locomotives, and track machinery, affects both human health and the environment. This study explores the application of machine learning (ML) models to quantify tram noise at sharp curves, considering variables such as weather conditions, train speed, crowd levels, and running directions. Data collection is carried out on a tram line in Birmingham, using an iPhone 11 to record acoustic data at a sample rate of 48 kHz. The noise is categorized into impact noise, rolling noise, flanging noise, and squeal noise based on frequency and power spectrum characteristics. Random Forests (RF) and Extreme Gradient Boosting (XGBoost) are employed to predict the root mean square (R.M.S) values of each type of noise. Results indicate that XGBoost outperformed RF with an R-2 up to 0.96 during k-fold cross-validation. This model provides a robust tool for railway operators to optimize noise control measures and contributes to improved compliance with environmental regulations and a better quality of life for communities near rail tracks.
