Sound attenuation performance and standards compliance

Noise Reduction Rating (NRR/SNR) and EN 352-2 certifications

3M™ E-A-R™ UltraFit™ earplugs boast an SNR of 35 dB, placing them among the highest-performing hearing protectors in their category.

This level of attenuation effectively covers noisy industrial environments: cutting workshops, foundries, construction sites, or machine rooms.

They are EN 352-2 certified, the reference European standard for earplugs. This certification guarantees that the product has been tested and validated by an independent notified body.

Attenuation values by frequency band (H, M, L) allow for selection based on the sound spectrum of the workstation:

• H (high frequencies): 36 dB
• M (medium frequencies): 33 dB
• L (low frequencies): 26 dB

For comparison, here is how the UltraFit™ positions itself against other common reusable earplugs:

Product	Manufacturer	SNR	Material	Standard
E-A-R™ UltraFit™	3M	35 dB	Soft polyurethane	EN 352-2
E-A-R™ Classic™	3M	28 dB	Insertion PU foam	EN 352-2

Honeywell Howard Leight MAX-1	Honeywell	37 dB	Insertion PU foam	EN 352-2

The UltraFit™ stands out for its preformed, no-roll design, which simplifies insertion and reduces fit errors, a key factor in maintaining real-world attenuation on the job.

Materials, ergonomics, and ease of insertion

Soft silicone and triple-flange stems: why it makes all the difference

3M™ E-A-R™ UltraFit™ earplugs are made of soft, hypoallergenic silicone. This material does not compress or swell in the ear canal and remains stable over time.

This is a fundamental difference compared to traditional polyurethane foam earplugs (such as the 3M™ E-A-R™ Classic™): no rolling between fingers, no waiting for them to expand. Just insert, and they are in place.

The triple-flange shape, three flexible stems that spread slightly in the canal, ensures a consistent seal without excessive pressure. Result: the plug stays in place even while moving, without causing pain after several hours of wear.

• Material: soft silicone, PVC and latex-free
• Shape: preformed triple-flange tip, universal size
• Insertion: direct, without prior compression
• Retention: stable even during head movements
• Cleaning: washable with soapy water, reusable

Product	Material	Insertion	Reusable	Typical usage
3M™ E-A-R™ UltraFit™	Soft silicone	Direct (triple-flange)	Yes	Prolonged wear, industrial environments
3M™ E-A-R™ Classic™	PU foam	Compression + waiting	No	Occasional use, disposable
3M™ E-A-R™ Soft Yellow Neons™	PU foam	Compression + waiting	No	Optimized comfort, disposable
Moldex® Spark Plugs®	PU foam	Compression + waiting	No	Occasional use, disposable

Comparison: 3M™ E-A-R™ UltraFit™ versus other earplugs on the market

The market for protective earplugs offers several technologies. Here is how the UltraFit™ positions itself against common alternatives.

Comparison table of main hearing protection models

Model	Manufacturer	Type	Material	SNR	Reusable	Typical usage
E-A-R™ UltraFit™	3M	Preformed triple-flange	Soft polymer	25 dB	Yes	Industry, prolonged use
E-A-R™ Classic™	3M	Expandable foam	PU foam	28 dB	No (single-use)	Maximum attenuation, occasional use
E-A-Rsoft™ Yellow Neons	3M	Expandable foam	PU foam	36 dB	No (single-use)	Very noisy environments
Moldex® Spark Plugs®	Moldex	Expandable foam	PU foam	35 dB	No (single-use)	Intensive industrial use
Moldex® Rockets®	Moldex	Preformed triple-flange	Soft thermoplastic	27 dB	Yes	Industry, repeated wear

Expandable foam earplugs (E-A-R™ Classic™, Moldex® Spark Plugs®) often offer a higher SNR. However, they require manual shaping before each insertion, which slows down the process.

The UltraFit™ stands out with its direct insertion, without rolling or compressing. A concrete advantage on production lines where hands are dirty or gloved.

Compared to the Moldex® Rockets®, its direct competitor in reusable preformed earplugs, the UltraFit™ offers a proven triple-flange shape and compatibility with neck cords, useful for avoiding loss in the workshop.

In summary: if the goal is reusable, quick-to-insert, and long-term comfortable protection, the E-A-R™ UltraFit™ is a solid choice. For maximum attenuation in extreme environments, high-SNR foam remains more suitable.

Recommended application areas and professional sectors

3M™ E-A-R™ UltraFit™ earplugs are designed for industrial and professional environments where noise regularly exceeds 85 dB. Their preformed triple-flange shape makes them particularly suitable for long workdays.

Here are the sectors where they are a natural choice:

At Dagobert Industrie, we recommend these earplugs for any station with continuous exposure, where wearing comfort directly influences effective compliance by operators.

FAQ - 3M™ E-A-R™ UltraFit™ Earplugs

1. What is the sound attenuation of E-A-R™ UltraFit™ earplugs?

3M™ E-A-R™ UltraFit™ earplugs have an SNR of 25 dB, placing them in the category of moderate-to-high attenuation hearing protection.

They are suitable for noisy environments up to approximately 100 dB, such as manufacturing workshops, construction sites, or logistics zones.

2. Are UltraFit™ earplugs reusable?

Yes. Unlike disposable foam earplugs (like 3M™ E-A-Rsoft™), UltraFit™ are designed to be washed and reused multiple times.

Their soft thermoplastic material resists repeated washing without deforming or losing its attenuation properties.

3. How do you insert them correctly?

UltraFit™ are inserted without rolling or twisting the stem: simply push them gently into the ear canal. The triple-flange design adapts to the shape of the ear.

This no-pre-handling insertion is a major advantage in environments where hands are dirty or gloved.

4. Do they fit all ear shapes?

UltraFit™ are available in two sizes (S and M/L) to fit narrow as well as wider ear canals. Choosing the right size is essential to ensure attenuation effectiveness.

At Dagobert Industrie, we offer both references so that every user finds the size adapted to their anatomy.
