BS EN 1793-4:2015

## BS EN 1793-4:2015 - Noise Barrier Acoustic Performance MeasurementThis British Standard, BS EN 1793-4:2015, specifies a method for measuring the acoustic performance of noise barriers used along transportation corridors. Compliance with this standard is essential for ensuring the effectiveness of noise reduction solutions and meeting regulatory requirements.### Key Specifications and Technical Details- **Title:** BS EN 1793-4:2015- **ISBN:** 978 0 580 86099 7- **Price:** £258.00- **Scope:** This standard covers the measurement of the acoustic performance of noise barriers, specifically the airborne sound insulation.- **Measurement Method:** The standard outlines a laboratory-based measurement procedure using a reverberation room test method to determine the sound reduction index (R) of noise barrier materials.- **Frequency Range:** The measurements are conducted across a frequency range of 100 Hz to 5 kHz, covering the most critical frequencies for environmental noise.- **Reporting:** The standard provides guidance on how to report the measured sound reduction index, including the presentation of results in graphical and tabular formats.### Benefits of ComplianceCompliance with BS EN 1793-4:2015 offers several key benefits for noise barrier manufacturers, installers, and project stakeholders:1. **Regulatory Compliance:** Meeting the requirements of this standard ensures that noise barriers comply with relevant legislation and regulations governing environmental noise control.2. **Acoustic Performance Verification:** The standardized measurement method provides a reliable and repeatable way to assess the sound insulation properties of noise barrier materials, allowing for accurate performance comparisons.3. **Quality Assurance:** Adherence to the standard's protocols helps to maintain consistent quality and performance across different noise barrier products and installations.4. **Improved Noise Reduction:** By using materials and designs that meet the sound insulation requirements of BS EN 1793-4:2015, noise barriers can achieve more effective noise reduction, improving the acoustic environment for nearby communities.5. **Compatibility with Other Standards:** This standard is part of the EN 1793 series, which covers various aspects of noise barrier performance, allowing for a comprehensive assessment of noise barrier systems.### ConclusionBS EN 1793-4:2015 is a critical standard for ensuring the acoustic performance of noise barriers used in transportation and infrastructure projects. By complying with this standard, manufacturers, installers, and project stakeholders can demonstrate the effectiveness of their noise reduction solutions, meet regulatory requirements, and contribute to the creation of a more sustainable and livable environment.
