EN 352 is a series of European standards that covers various types of hearing protection devices, including earplugs. These standards specify requirements and testing methods to ensure the effectiveness and safety of hearing protection products. When it comes to earplugs, several parts of the EN 352 series are relevant:
EN 352-2: Earplugs
EN 352-2 specifically addresses earplugs used as hearing protection devices. It outlines requirements and testing methods for earplugs, including aspects such as noise reduction, comfort, durability, and safety.
EN 352-7: Level-dependent Earplugs
This part of the standard focuses on level-dependent earplugs, which are designed to offer variable protection based on noise levels. They allow wearers to hear low-level sounds, such as speech or warning signals, while protecting against high-level noise. EN 352-7 sets requirements and testing methods for such devices.
EN 352-8: Entertainment Audio Earplugs
EN 352-8 is relevant for earplugs designed for recreational or entertainment purposes, such as attending concerts or nightclubs. It addresses requirements for noise reduction and sound quality while maintaining the user’s ability to enjoy music or other forms of entertainment.
Each of these standards specifies criteria related to noise reduction, frequency range, comfort, fit, clamping force, durability, and safety. Earplug manufacturers must conform to these standards to ensure that their products provide effective hearing protection and meet safety requirements.
When selecting earplugs for hearing protection, it’s essential to consider the specific requirements of your environment and the level of noise reduction needed. Always choose earplugs that comply with the relevant EN 352 standard and follow the manufacturer’s instructions for proper fitting and use to ensure optimal protection for your hearing.
