What is BS EN 61672-2018

BS EN 61672-2018, also known as "Electroacoustics – Sound level meters", is a technical standard that sets requirements for sound level meters used in various industries. This standard specifies the characteristics and performance criteria of sound level meters, ensuring accurate and reliable measurement of sound levels.

Key Features of BS EN 61672-2018

The BS EN 61672-2018 standard outlines several key features that a sound level meter must possess to meet its requirements. These features include:

A-weighting and C-weighting frequency filters: The standard mandates the inclusion of frequency filters in sound level meters to account for human hearing sensitivity.

Fast, slow, and impulse time weightings: Sound level meters must be capable of measuring sound levels over different time intervals to capture both continuous and impulsive noises.

Measurement range and dynamic range: The standard defines the minimum and maximum sound pressure levels that the meter should measure accurately without distortion.

Frequency range: Sound level meters must cover an appropriate frequency spectrum to capture sounds within the audible range.

Applications of BS EN 61672-2018

The BS EN 61672-2018 standard applies to a wide range of industries where accurate sound level measurement is crucial. Some common applications include:

Environmental monitoring: Sound level meters are used to assess noise pollution in residential areas, construction sites, airports, and industrial facilities.

Occupational health and safety: The standard ensures that sound level meters provide accurate measurements for assessing workplace noise levels, protecting employees from hearing loss and other related health issues.

Product testing and certification: Sound level meters that comply with BS EN 61672-2018 are used in laboratories to assess the acoustic performance of various products, such as household appliances, musical instruments, and automotive components.

Entertainment industry: Sound level meters are essential tools for audio engineers and event organizers to maintain safe sound levels during concerts, festivals, and other live performances.

Conclusion

BS EN 61672-2018 plays a crucial role in ensuring accurate and standardized sound level measurements across different industries. By complying with this standard, sound level meters can provide reliable data for assessing noise pollution, protecting workers' hearing health, and evaluating product acoustic performance. The standard's comprehensive guidelines and requirements make it an invaluable reference for manufacturers, regulators, and professionals involved in sound level measurement and control.
