Acoustic Simulation Study of Subway Underwater Tunnels Based on EASE

The urban rail transit system is rapidly expanding due to its energy efficiency, ecological friendliness, and high capacity. However, the issue of noise pollution has received great attention. In order to solve the problem of excessive noise when subway tunnels pass through canals in specific cities, a sound field model was established using experimental data from existing subway systems. Calibrate the model until the simulation error is less than 3 decibels to verify its accuracy. This method will be applied to the sound field modeling of future target subway sections.
