What is EN ISO 14127:2021?

EN ISO 14127:2021 is a technical standard that provides guidelines for the measurement and assessment of noise emitted by machinery and equipment. It specifies the procedures and instruments required to determine the sound power levels of machines, which helps in evaluating their acoustic performance. This standard was developed by the International Organization for Standardization (ISO) and represents a valuable tool for manufacturers, regulators, and users of machinery who are concerned about noise control and reduction.

Importance of Noise Measurement

Noise from machinery and equipment can have significant effects on human health and safety, as well as the environment. Excessive noise exposure can lead to hearing loss, stress, and even cardiovascular problems. Therefore, it is crucial to measure and assess the noise levels produced by machinery to ensure compliance with relevant regulations, protect workers' well-being, and minimize environmental impact.

Measuring Sound Power Levels

The EN ISO 14127:2021 standard outlines the procedures for measuring sound power levels emitted by machines. It specifies the use of precision sound intensity measurements or sound pressure measurements combined with statistical methods to calculate sound power levels. These measurements provide objective data regarding a machine's noise emissions, allowing manufacturers to compare different models, evaluate design modifications, and implement effective noise control measures during machine development stages.

Assessing Compliance and Control Measures

In addition to providing guidelines for noise measurement, EN ISO 14127:2021 also offers criteria for assessing compliance with noise emission limits and provides recommendations for noise control measures. By adhering to these guidelines, manufacturers can ensure that their machinery meets the required noise standards and avoid potential legal issues. Furthermore, users of machinery can refer to this standard to gain insight into noise reduction strategies and select quieter equipment that contributes to a safer and more comfortable working environment.
