What is EN ISO 9613-2:2018 ?

EN ISO 9613-2:2018 is a crucial standard for sound measurement and prediction. It provides a standardized methodology for measuring and predicting outdoor sound propagation, ensuring consistency and accuracy in acoustic assessments carried out in different locations around the world. In this article, we will delve into the specifics of the standard and its importance in sound engineering and measurement.

Sound Propagation and EN ISO 9613-2:2018

Sound travels in waves and the way these waves propagate can vary depending on numerous factors such as distance, obstacles, and environmental conditions. In everyday life, we often encounter situations where sound needs to be measured or predicted accurately. This may include assessing the impact of noise pollution from industrial sites, calculating noise levels near busy roads, or determining the acoustic parameters of public spaces like parks or stadiums.

The Importance of EN ISO 9613-2:2018

EN ISO 9613-2:2018 provides a standardized methodology for measuring and predicting outdoor sound propagation, ensuring consistency and accuracy in acoustic assessments carried out in different locations around the world. The standard outlines detailed procedures and equations for calculating sound pressure levels (SPL) at specified distances from a noise source, taking into account various factors such as the source's characteristics, atmospheric conditions, ground effects, and the presence of barriers or reflectors.

EN ISO 9835:2018

EN ISO 9835:2018 is a technical standard that lays down requirements for the writing and presentation of technical documentation. The main purpose of EN ISO 9835:2018 is to ensure consistency and clarity in technical documentation across various industries.

Key Requirements of EN ISO 9835:2018

EN ISO 9835:2018 outlines several key requirements for technical documentation, including:

Clarity: Technical documentation should be clear and concise, using appropriate language and formatting.

Accuracy: Technical documentation should be accurate and reflect the true state of the technology or system.

Consistency: Technical documentation should be consistent in format, language, and style across different parts of the documentation.

Contextualization: Technical documentation should be contextualized, providing appropriate information about the intended audience, purpose, and scope.

Relevance: Technical documentation should be relevant to the subject matter and the intended audience.

Appropriateness: Technical documentation should be appropriate in terms of its form and style, reflecting the needs and capabilities of the audience.

Conclusion

EN ISO 9613-2:2018 is a crucial standard for sound measurement and prediction, providing a standardized methodology for measuring and predicting outdoor sound propagation. The standard ensures consistency and accuracy in acoustic assessments carried out in different locations around the world. Additionally, EN ISO 9835:2018 is a technical standard that lays down requirements for the writing and presentation of technical documentation, aiming to ensure consistency and clarity in technical documentation across various industries.
