What is BS EN 45516-2:2017?

BS EN 45516-2:2017 is a technical standard that specifies the testing methods and requirements for airborne sound insulation in buildings. It provides guidelines for evaluating the acoustic performance of building elements such as walls, floors, ceilings, doors, and windows.

Understanding the Basics

Sound insulation plays a crucial role in creating comfortable and peaceful indoor environments. BS EN 45516-2:2017 sets out the procedures for measuring and assessing the sound insulation properties of building components, enabling designers and engineers to ensure compliance with relevant regulations and standards.

The standard defines various terms and concepts related to sound insulation, including sound pressure levels, transmission loss, single-number quantities (Rw, DnT,w), and flanking transmission. It also outlines the different test configurations and conditions, providing clear instructions on how to conduct tests accurately and consistently.

Testing Methods and Requirements

BS EN 45516-2:2017 specifies the equipment and apparatus required for testing, including reference sound sources, loudspeakers, and microphones. It describes the test setup, which typically involves placing the test specimen between two rooms (a source room and a receiving room) and generating sound in the source room while measuring sound levels in both rooms.

The standard also outlines the calculation procedures for determining the sound insulation performance based on the measured data. It includes corrections for background noise, reverberation time, and frequency-dependent properties of the building component under test. These calculations help establish accurate values for sound reduction indexes and other relevant parameters.

Benefits and Applications

BS EN 45516-2:2017 provides a comprehensive framework for assessing and comparing the acoustic performance of building elements. Compliance with this standard ensures that buildings meet the necessary sound insulation requirements, promoting comfortable living and working environments.

The standard is widely used by architects, engineers, and acoustic consultants in the design and construction phases of various types of buildings, including residential, commercial, educational, healthcare, and institutional. It helps to optimize the acoustic performance of spaces, reduce noise transmission, and enhance overall comfort and wellbeing.

In conclusion, BS EN 45516-2:2017 is a vital technical standard that guides the evaluation of airborne sound insulation in buildings. Its testing methods and requirements enable stakeholders to assess the acoustic performance of building components accurately. By adhering to this standard, designers and engineers can create indoor environments that prioritize comfort and minimize noise disturbance, ultimately benefiting occupants around the world.
