What is BS EN 352-7 about?
BS EN 352-7 is the seventh part of the hearing protectors multi-series. BS EN 352-7 is a European standard that ensures safety requirements for hearing protectors are met.
BS EN 352-7 applies to level-dependent earplugs. BS EN 352-7 specifies requirements on construction, design, performance, marking, and user information related to the inclusion of the level-dependent functionality.
The requirements of BS EN 352-7 are concerned with the level-dependent performance of the earplugs. The criterion levels within BS EN 352-7 are determined to limit the sound pressure level effective to the ear to 85 dB(A).
Who is BS EN 352-7 for?
BS EN 352-7 on safety requirements for level-dependent earplugs is useful for:
- Hearing protector device manufacturers
- Quality control personnel
- Hearing protector device designers
- Acoustic engineers
Why should you use BS EN 352-7?
Level-dependent earplugs are designed to provide restoration of external sounds while providing attenuation of sounds at high levels.
BS EN 352-7 provides you with the performance requirements for level-dependent earplugs that enable soft noises to be conveyed with full strength while eliminating any high frequency or impulse noise, hence improving the quality and performance of level-dependent earplugs.
Overall, BS EN 352-7 covers all the safety requirements for level-dependent earplugs that assist you to produce high-quality level-dependent earplugs while eliminating hazardous steady-state or impulse noise.
