Gehörschützer - Sicherheitstechnische Anforderungen - Teil 7: Pegelabhängig dämmende Gehörschutzstöpsel
Dieses Dokument ist anzuwenden für pegelabhängige Gehörschutzstöpsel. Es legt für die Integration der pegelabhängigen Funktionalität Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen fest.
Pegelabhängige Gehörschutzstöpsel sind dazu konstruiert, die Wiedergabe von Umgebungsgeräuschen zu ermöglichen, während sie bei hohen Pegeln eine Dämmung des Schalls bewirken. Sie können für die Anwendung in Umgebungen mit intermittierendem oder Impulslärm, in der gleichzeitig äußere akustische Warnsignale gehört werden müssen, eingesetzt werden. Dieses Dokument behandelt diejenigen Gehör¬schutzstöpsel, die mit einem elektronischen Schaltkreis für die Schallwiedergabe ausgestattet sind.

Overview
EN 352-7:2020 - published by CEN - is the European standard for level-dependent earplugs. It sets safety and performance requirements specific to earplugs that use an electronic sound restoration circuit to restore low-level external sounds while attenuating high-level sounds. The standard covers construction, design, performance, marking and user information required for the inclusion of level-dependent functionality and supports conformity with EU Regulation (EU) 2016/425 for personal protective equipment where cited in the Official Journal.
Key Topics
- Scope and product type: Applies only to earplugs fitted with an electronic sound restoration circuit (level-dependent earplugs).
- Performance criteria: Defines criterion levels (H, M, L) that limit effective sound pressure at the ear to target levels; tests follow EN 13819-3:2019 (see clause 7.2.3).
- Minimum criterion levels:
- For products intended for impulse-type noise only: H = 85 dB(A), M = 85 dB(A), L = 85 dB(A)
- For products not intended for impulse-only environments: H = 97 dB(A), M = 96 dB(A), L = 94 dB(A)
- If level-dependent function causes no change at L, the L requirement may not apply.
- Marking and information: Uses EN 352-2:2020 marking requirements (no additional marking required).
- Manufacturer instructions: Must include reference to EN 352-7:2020, identification of level-dependent functionality, measured criterion levels, battery charging/changing instructions, operational checks, battery-life warnings and suitability warnings (e.g., if not suited for high continuous noise).
- Compliance relationship: Annex ZA maps EN 352-7 clauses to essential requirements of Regulation (EU) 2016/425.
Applications and Who Uses It
- Manufacturers and R&D teams designing level-dependent earplugs to meet European safety and performance requirements.
- Test laboratories and certification bodies performing acoustic tests and issuing conformity assessments.
- Occupational health & safety professionals, procurement officers and PPE purchasers selecting hearing protection for workplaces where situational awareness is required (intermittent, impulsive or environments with warning signals).
- Product designers and QA teams documenting marking, battery guidance and user information.
Practical uses include selecting and validating earplugs for industries such as construction, aviation ground operations, shooting ranges and manufacturing lines where hearing protection must allow detection of speech or warning signals while protecting from hazardous noise.
