title: Various types of subway station noise monitoring data

description: In this study, comprehensive monitoring was conducted on the noise
 environment on the platforms during operational hours at four distinct
 types of subway stations within the capital's metro network. To
 ensure precise data collection, four different noise and sound pressure
 measurement points were strategically positioned in the middle and at both
 ends of each station platform. Subsequently, the platform noise data was
 continuously monitored throughout the day, yielding a time series of
 original data on sound pressure levels for standardized continuous
 monitoring of the platform. The collected results spanning the entire
 operation period were organized into hourly sets, encompassing information
 on noise sources such as vehicles entering and leaving the station, the
 opening and closing of train doors, and platform announcements. This
 dataset provides original data on noise sources at subway platforms
 throughout the all-day train operation period, aiding researchers in
 understanding the sources and levels of noise at subway station platforms.
 Additionally, this research supports noise control on subway platforms and
 provides a scientific basis for predicting the acoustic environment of
 rail transit stations and improving the platform acoustic environment.

 [https://doi.org/10.5061/dryad.qz612jmqz](https://doi.org/10.5061/dryad.qz612jmqz) ## Description of the data and file structure The raw data is organized in a zipped file named "Various types of subway station noise monitoring data". The file size is 300GB(546GB before compression).It comprises samples collected from continuous monitoring of subway trains across nine stations during the entire operational period. The raw data was initially extracted from the RYS-INV3062C data acquisition system in .sts and .tsp formats, which include sound signals from actual measurements and details such as the time of measurement. The measurement points, located at the center of each station’s platform and equipped with four sensors, serve as the actual samples. Samples from sensors oriented in the same direction were selected to compile the final dataset, segmenting the continuous monitoring data into one-hour time-series samples. The original data, provided in .sts and .tsp files, includes parameters such as sampling frequency, the number of sampling points, and the amplitude of noise signals at each point. The data is organized into 15 subfolders labeled with the respective station abbreviations, each containing raw data files for noise measurements under different conditions. Additionally, a data format conversion script is provided to facilitate the transformation of the original data into a more user-friendly .txt format.The script is MATLAB code, in use need to put the.sts and.tsP and the script file in the same folder, run the script file can be converted to txt format data file, need to convert the format can also be changed according to their own needs. If you have a legitimate DASP software provided by B&K, you can directly open .sts and .tsp files. One .sts file and one .tsp file are a group corresponding to a group of noise monitoring results.
