What is EN 50332-2:2012?

The technical standard EN 50332-2:2012 focuses on the measurement of sound pressure levels emitted by audio equipment. It specifically addresses headphones, earphones, and other portable audio devices. This article will provide an in-depth analysis of the standard, its requirements, and its implications for both manufacturers and consumers.


EN 50332-2:2012 was developed by the European Committee for Electrotechnical Standardization (CENELEC) to establish uniform guidelines for testing the maximum sound pressure level generated by personal audio devices. The increased usage of portable audio equipment led to concerns about potential hearing damage caused by excessively loud music or other audio content.

Requirements of EN 50332-2:2012

The standard sets specific limits for sound pressure levels based on different modes of listening, such as continuous, intermittent, and peak exposure. It also provides guidelines for measuring these levels using standardized equipment and defines the necessary conditions for accurate measurements. Furthermore, it outlines procedures for reporting test results and labeling products accordingly.

Implications for Manufacturers and Consumers

Manufacturers need to ensure that their audio devices comply with the requirements of EN 50332-2:2012 to market their products in the European Union. Failure to meet the standard's guidelines may result in legal consequences and product recalls. On the other hand, consumers can make informed decisions by looking for products labeled with the EN 50332-2:2012 certification mark, ensuring their safety and enjoyment while using personal audio devices.
