Research results and noise frequency characteristics;
--- Deleted the train formation (adjacent vehicles) in ISO 3095:2013 to meet the actual situation of railway and urban rail transit vehicles in my country:
Measurement requirements;
---Added other requirements for uniform speed test (see 6:8) to meet the application requirements of environmental impact assessment or dynamic engineering acceptance in my country;
--- Added the measurement and data processing method of the fluctuation degree AR of the noise emitted by railway locomotives and vehicles (see Appendix G) to meet the requirements of my country
Need for assessment of track acoustic properties:
The following editorial changes were made to this document:
--- In order to coordinate with the existing standards, the name of the standard is changed to "Measurement of Noise Emitted by Acoustic Railway Locomotives and Vehicles";
--- Added uncertainty calculation examples;
--- Added informative references to GB/T 3240 and TB10761;

Acoustics - Measurement of noise emitted by rolling stock
1 Scope
This document describes the methods and conditions for measuring the levels and spectral characteristics of noise emitted by railway rolling stock and other various types of rolling stock:
This document applies to:
--- Type test of rolling stock;
---Dynamic acceptance of projects;
---Periodic supervision inspection;
--- Conventional noise measurement;
--- Environmental impact assessment measurement:
The results can be used to:
--- Characterize the noise emission characteristics of railway and urban rail transit trains;
--- Compare the emission noise of various types of rolling stock in a specific section;
---Get basic train sound source data:
Note 1: The type test measurement method is engineering grade (level 2, accuracy is ±2dB): Engineering grade is the preferred level for noise disclosure (see
GB/T 19052): If the measurement conditions (such as vehicle conditions or track conditions, etc:) are relaxed, such as monitoring and measuring trains during operation, the results will no longer meet the requirements:
Engineering grade:
Note 2: The acceleration or deceleration measurement methods are all simple level:
NOTE 3 Additional guidance for measurements on light rail vehicles under specific conditions is given in Annex A:
