Overview
EN 352-2:2020+A1:2024 - published by CEN - is the European standard that sets general requirements for earplugs as personal hearing protectors. It covers construction, design, performance, marking and user information for aural, semi-aural, disposable, re‑usable, custom‑moulded and banded earplugs. The standard requires declaration and measurement of sound attenuation in accordance with EN ISO 4869-1:2018 and addresses ergonomic interaction between the user, the device and the working environment. Amendment A1 (2024) adds/updates requirements primarily for banded earplugs.
Key topics and technical requirements
- Sound attenuation: Measured per EN ISO 4869-1:2018; manufacturers must declare attenuation values and meet specified minimum attenuation requirements to support correct product selection.
- Performance testing: Physical and acoustic test methods referenced (e.g., EN 13819-1:2020+A1:2024 for physical tests and EN 13819-2:2020 for acoustic test methods).
- Sizing and adjustability:
- Nominal diameter or range must be reported for aural earplugs (except custom‑moulded and semi‑aural types).
- Specific adjustability and sizing requirements for banded earplugs (medium/small/large size ranges; over‑the‑head, behind‑the‑head, under‑the‑chin configurations).
- Materials and construction: Requirements for materials and robustness (drop resistance, low‑temperature resistance as applicable), cleaning and ignitability.
- Marking and user information:
- Mandatory marking and packaging information.
- Clear instructions for fitting, care, limitations and warnings. Applies to users able to follow instructions and give feedback on fit/performance.

Introduction
This document sets requirements for personal hearing protection devices in relation to Regulation
(EU) 2016/425 on personal protective equipment.
The particular requirement in relation to the ability of hearing protectors to reduce noise below limit
levels is addressed in the standard by requiring the sound attenuation of the hearing protectors,
measured in accordance with EN ISO 4869-1, to be not less than a specified minimum. Further, by
requiring that the measured sound attenuation be declared, the selection of suitable hearing protectors
for individual circumstances can be undertaken according to established practice.
EN 352-2 is part of a family of standards describing product requirements for hearing protectors:
— EN 352-1, Hearing protectors — General requirements — Part 1: Earmuffs
— EN 352-2, Hearing protectors — General requirements — Part 2: Earplugs
— EN 352-3, Hearing protectors — General requirements — Part 3: Earmuffs attached to head
protection and/or face protection devices
— EN 352-4, Hearing protectors — Safety requirements — Part 4: Level-dependent earmuffs
— EN 352-5, Hearing protectors — Safety requirements — Part 5: Active noise reduction earmuffs
— EN 352-6, Hearing protectors — Safety requirements — Part 6: Earmuffs with safety-related audio
input
— EN 352-7, Hearing protectors — Safety requirements — Part 7: Level-dependent earplugs
— EN 352-8, Hearing protectors — Safety requirements — Part 8: Entertainment audio earmuffs
— EN 352-9, Hearing protectors — Safety requirements — Part 9: Earplugs with safety-related audio
input
— EN 352-10, Hearing protectors — Safety requirements — Part 10: Entertainment audio earplugs
Test methods for these requirements for all types of hearing protectors are described in the following
standards:
— EN 13819-1, Hearing protectors — Testing — Part 1: Physical test methods
— EN 13819-2, Hearing protectors — Testing — Part 2: Acoustic test methods
— EN 13819-3, Hearing protectors — Testing — Part 3: Supplementary acoustic test methods
An associated standard EN 458 covers selection, use, care and maintenance of hearing protection.
The parts of EN 352, other than parts 1, 2 and 3, cover the performance of functions additional to
passive hearing protection. Hearing protectors which incorporate one or more of these functions are
subject to the requirements and tests of each of the relevant parts of EN 352-4 to −10, in addition to
that of parts 1, 2 or 3, as appropriate.
The requirements of this document are concerned primarily with the physical and acoustic
performance of the earplugs. It covers disposable, re-usable, custom moulded and banded earplugs.
In order to assist users to select the correct size(s) of earplugs, a nominal diameter, or range of
diameters, of the earplugs is required to be declared (except for custom moulded and semi-aural
earplugs).
In the case of banded earplugs, the standard specifies sizing requirements which enable the majority of
the user population to be fitted satisfactorily by “medium size range” earplugs. Individuals with other
sizes can be accommodated by “small size range” or “large size range” earplugs, which are required to
be accompanied by information regarding the range of sizes which they are designed to fit.
The standard also calls for the values of sound attenuation provided by the earplugs (measured in
accordance with EN ISO 4869-1) in order to assist users in selecting the most appropriate model of
earplugs for their needs. Minimum values of sound attenuation are also specified.
1 Scope
This document specifies requirements on construction, design, performance, marking and user
information for earplugs.
In particular, it specifies requirements regarding the sound attenuation of the earplugs, measured in
accordance with EN ISO 4869-1:2018.
This document applies to earplugs designed for users who are able to follow supplied instructions and
understand the related risks, can fit the earplugs correctly and can give feedback on the performance.
Ergonomic aspects are addressed by taking into account, within the requirements, the interaction
between the user, the device and where possible the working environment in which the device is likely
to be used (see Annex ZA and EN 458).

The EN 352-2:2020+A1:2024 standard provides comprehensive guidelines for earplugs, detailing the necessary requirements for their construction, design, performance, marking, and user information. By emphasizing sound attenuation, as measured according to EN ISO 4869-1:2018, the standard ensures that earplugs deliver effective noise reduction, catering specifically to environments where noise exposure is a concern. A significant strength of this standard lies in its focus on user engagement. It outlines the capabilities expected from users, such as the ability to follow instructions, understand associated risks, and fit the earplugs correctly. This user-centric approach enhances the overall effectiveness of hearing protection by ensuring that users are equipped to provide feedback on the earplugs’ performance, thereby fostering continual improvement in design and functionality. Ergonomics is another critical dimension of EN 352-2:2020+A1:2024, as it addresses the interaction between the user, the earplug device, and the working environment. By considering ergonomic aspects, the standard seeks to maximize user comfort and effectiveness, recognizing the importance of a well-designed earplug in reducing fatigue and promoting compliance among users in diverse settings. Annex ZA and EN 458 provide additional insights into these ergonomic considerations. Overall, the EN 352-2:2020+A1:2024 standard serves as a crucial reference for manufacturers, ensuring that earplugs meet high construction and performance standards while enhancing user interaction and comfort. Its relevance extends across industries where hearing protection is necessary, aligning product performance with user safety and satisfaction. This makes it an indispensable document for stakeholders focused on the development and implementation of effective hearing protectors specifically in the form of earplugs.
