SF-EM01 Helmet-Mounted Hearing Protection

Product Type: Passive Safety Helmet Earmuffs | SNR 29 dB / NRR 23 dB

SF-EM01 integrates tested hearing protection directly with a compatible safety helmet, eliminating the need for a separate headband. Tested on the SF-06B helmet, it delivers SNR 29 dB and NRR 23 dB attenuation. Adjustable pivot arms, replaceable cushions and S/M/L fit ranges provide practical protection for construction, manufacturing and other high-noise workplaces.

Overview

SF-EM01 mounts directly to the side slots of a compatible safety helmet. Adjustable pivot arms allow the ear cups to move between working and standby positions, while cushioned seals help maintain a secure fit around the ears.

The tested SF-EM01 and SF-06B combination provides SNR 29 dB under EN 352-3:2020 and NRR 23 dB under ANSI S3.19-1974 (R2007). Its adjustable S/M/L fit range, replaceable cushions and liners support daily industrial use and easier maintenance.

01 Tested Noise Attenuation

Provides SNR 29 dB and NRR 23 dB attenuation in the tested SF-EM01 and SF-06B configuration, supporting selection for measured workplace noise conditions.

02 Helmet-Integrated Design

Direct helmet mounting removes the need for an over-the-head band and allows head and hearing PPE to work together as one practical system.

03 Adjustable Working Positions

Pivoting support arms allow users to position the cups over the ears during noisy work or move them away when hearing protection is temporarily not required.

04 Replaceable Wear Components

Replaceable cushions and liners support routine hygiene, maintenance and longer service life for industrial users.

Application

Designed for workers who require compatible head and hearing protection in high-noise environments. Actual selection must be based on workplace noise measurements, correct fitting and confirmed helmet compatibility.

What is the noise reduction rating of SF-EM01?

SF-EM01 provides SNR 29 dB under EN 352-3:2020 and NRR 23 dB under ANSI S3.19-1974 (R2007) in the tested configuration. SNR and NRR are based on different rating systems and should not be directly converted.

Is SF-EM01 covered by an EU certificate?

SF-EM01 is covered by a Module B EU Type-Examination Certificate as Category III PPE to EN 352-3:2020. CE marking for production also requires the applicable ongoing conformity-assessment route and an EU Declaration of Conformity.

Which safety helmets are compatible?

The supplied reports specifically cover SF-EM01 mounted on the SF-06B helmet. Compatibility with other helmets, side slots or mounting adapters must be confirmed before purchase and should not be assumed.

Can the earmuffs be moved away from the ears?

Yes. The pivoting mounting arms allow the cups to move between working and standby positions while remaining attached to the helmet.

Are the cushions and liners replaceable?

Yes. The EN 352-3 test report records both the ear cushions and liners as replaceable, supporting easier cleaning and maintenance.

Is one size suitable for different users?

The tested product passed the small, medium and large adjustment ranges. Correct adjustment and a complete seal around the ears remain essential for effective protection.

Can the color and packaging be customized?

Color matching, branding and packaging options are available subject to production confirmation. The materials, sealing structure and mounting components must remain consistent with the approved or tested configuration.

Will users always receive 29 dB of protection?

Not necessarily. Laboratory attenuation values are used for product comparison. Actual workplace protection can be lower due to incorrect adjustment, poor cushion sealing, incompatible helmets, hair, eyewear or other PPE interfering with the fit.
