SIST EN 16272-3-2:2023/oprA1:2024

Overview

SIST EN 16272-3-2:2023/oprA1:2024 is a vital European standard developed by CEN under Technical Committee CEN/TC 256 focused on railway applications. This standard addresses noise barriers and related devices that impact airborne sound propagation near railway infrastructure. It specifies a test method for determining the acoustic performance of such noise reduction devices using a normalized railway noise spectrum and single number ratings aimed at direct sound field applications.

This standard excludes devices focused on ground-borne vibration attenuation or on-board noise control, maintaining a specific scope to airborne noise from railway operations. It plays a crucial role in the evaluation and design verification of infrastructures that aim to reduce railway noise pollution effectively.

Key Topics

• Normalized Railway Noise Spectrum: Provides a standardized frequency spectrum for railway noise to ensure consistent evaluation across different devices and installations.
• Single Number Ratings (SNR): Simplified numerical indices that represent acoustic performance for direct sound fields, allowing easier assessment and comparison.
• Test Methods: Defines precise measurement and calculation procedures for assessing noise barrier performance with regard to airborne sound.
• Acoustic Elements and Accessories: Specifies requirements and modifications related to the acoustic elements and installation posts influencing sound attenuation.
• Measurement Uncertainty: Introduces reproducibility data and updated formulas to account for uncertainty in sound level measurements, ensuring reliability of test results.

Applications

This standard is essential for a variety of stakeholders involved in the railway sector, including:

• Railway infrastructure designers and engineers: To assess and optimize the efficacy of noise barriers in mitigating railway noise pollution.
• Noise barrier manufacturers: To test and verify the acoustic properties of their products using standardized methods.
• Environmental consultants and regulators: For noise impact assessments and regulatory compliance related to railway infrastructure projects.
• Urban planners: To incorporate effective noise mitigation solutions in areas where railways are close to residential or noise-sensitive zones.
• Research and Development: For developing new materials and technologies in noise reduction tailored to railway environments.

By using EN 16272-3-2:2023, stakeholders can ensure products and solutions conform to harmonized sound performance criteria, facilitating interoperability and smoother regulatory approvals across Europe.

Related Standards

EN 16272-3-2:2023 is part of the broader EN 16272 series on railway noise reduction, specifically focused on airborne sound and noise barriers. Related standards within this series include:

• EN 16272-6:2023: Defines additional acoustic element requirements referenced in the amendments of Part 3-2.
• EN 16272-4:2016: Covers other test procedures related to noise barrier performance under different conditions.
• Other parts of EN 16272 dealing with vibration attenuation and onboard noise control, although not covered here, complement the full approach to comprehensive railway noise management.

Utilizing this set of standards allows for a complete and standardized approach to controlling railway noise emissions, enhancing both environmental quality and community wellbeing near rail corridors.
