EN 47991 is a technical standard that specifies the requirements for measuring airborne noise emitted by machinery and equipment. It provides guidelines for acoustic testing and establishes limits for noise emission in various industrial environments.
Why is EN 47991 important?
EN 47991 plays a crucial role in ensuring the safety and well-being of workers in noisy environments. Excessive noise exposure can lead to hearing loss, stress, and other health issues. By setting noise limits and providing methods for measurement, this standard helps companies to assess and reduce noise emissions from their equipment, ultimately protecting employees and improving overall workplace conditions.
How does EN 47991 work?
EN 47991 outlines the procedures and instrumentation required for measuring noise levels accurately. The standard specifies the use of sound intensity and sound pressure methods, along with detailed instructions on positioning microphones and determining measurement positions and distances. Additionally, it offers guidance on calculating average sound pressure levels and evaluating frequency spectra.
Compliance and certification
In order to comply with EN 47991, manufacturers must ensure that their equipment meets the specified noise emission limits. The standard provides information on product labeling requirements and documentation necessary for demonstrating compliance. Compliance with EN 47991 can be verified through independent testing and certification by accredited laboratories, giving confidence to both manufacturers and end users that noise emissions are within acceptable levels.
In conclusion, EN 47991 is an essential technical standard that promotes safe and healthy working conditions by regulating noise emissions from machinery and equipment. Adhering to this standard helps companies protect their employees from excessive noise exposure and ensures compliance with legal requirements. By reducing noise levels, businesses can also enhance the overall quality of their products and improve customer satisfaction.
