What SN 520181:2020 covers

The SN 520181:2020 standard focuses on the requirements for noise protection in building construction, particularly concerning the impact of both airborne and impact noise. It outlines measures that must be taken to safeguard occupants from external noises, such as traffic and industrial sounds, as well as internal noises generated by activities within the building, like footfall and mechanical systems. Additionally, the standard provides guidelines on the design and construction of buildings to enhance acoustic comfort and ensure compliance with noise regulations. Notably, the standard does not cover specialized acoustic treatment for performance spaces or industries with unique noise requirements, such as theaters or concert halls.

Who needs to comply with SN 520181:2020

SN 520181:2020 is relevant to a wide range of stakeholders in the construction materials and buildings industry. This includes architects, civil engineers, contractors, and project managers who are responsible for designing and constructing residential and commercial buildings. Additionally, manufacturers of construction materials, such as insulation and soundproofing products, must ensure their products meet these standards. Compliance is essential for companies of all sizes, from small construction firms to large multinational corporations, as well as regulatory bodies overseeing building codes and standards. Ultimately, anyone involved in the building process must be aware of and adhere to these noise protection requirements to promote better living and working environments.

Key requirements

• Airborne Noise Protection: Defines the minimum sound insulation values for walls, floors, and ceilings to mitigate noise from external sources.
• Impact Noise Control: Establishes criteria for minimizing impact noise from foot traffic and other activities, focusing on structural design and materials used.
• Technical Installations: Outlines the requirements for noise control from mechanical and electrical systems, ensuring they do not contribute excessively to the overall noise levels in buildings.
• Measurement Methods: Specifies standardized methods for measuring noise insulation performance in buildings to ensure compliance with the established requirements.
• Documentation and Compliance: Mandates proper documentation of all noise protection measures taken during construction and establishes auditing procedures to verify compliance.

These requirements are typically audited through a combination of documentation review, on-site assessments, and noise measurement testing.

How to implement SN 520181:2020

Implementing SN 520181:2020 involves several systematic steps to ensure compliance with the standard's requirements. First, a gap analysis should be conducted to identify existing noise protection measures and areas that require enhancement. Following this, comprehensive documentation of the noise protection strategies should be prepared, detailing the materials and methods used. Training sessions for relevant personnel, including architects and contractors, should be organized to ensure everyone understands the standards and their implementation. An internal audit should be performed to assess the effectiveness of the implemented measures and resolve any issues. Finally, a certification audit can be arranged to validate compliance with SN 520181:2020, which may involve external auditors reviewing the documentation and conducting site inspections. For more detailed guidance, an implementation guide should be consulted.
