MSA SoundControl SH Hard Hat Earmuffs

These dielectric earmuffs attach to MSA slotted full-brim hard hats for hearing protection on job sites. They provide a Noise Reduction Rating of 25 dB and meet ANSI S3.19-1974 and CSA Class A standards. The gray foam cushions and black polymer band suit workers who need compatible protection without electrical conductivity.

Spring Design and Three Wearing Positions

A spring mechanism delivers low clamping pressure for comfort during extended shifts. Three distinct wearing positions let the user adapt the fit to different tasks or headgear configurations. The cups grip securely for easy adjustment even when the wearer has gloves on, supporting quick changes in noisy environments.

25 dB Noise Reduction Rating

The 25 dB rating determines whether this model matches the noise exposure level required by the safety plan. Buyers needing higher attenuation for very loud environments should verify if this value meets their specific regulatory or site requirements. The dielectric construction also makes it the correct choice where non-conductive gear is mandated.

Questions about this item

What noise reduction rating does the ANSI S 3.19-1974 standard give these earmuffs?

The ANSI S 3.19-1974 rating on this model is 25 dB, which is the measured attenuation used for CSA Class A compliance.

Which hard hat model must I have for the 10129327 earmuffs to mount correctly?

They fit only MSA slotted full-brim hard hats, specifically the compatible manufacturer model number 10003360.

How do I switch the SoundControl SH earmuffs into the third wearing position without removing my hard hat?

Pivot each cup upward until it locks over the headband; the spring design holds it there so you can lower the cups again with gloved hands.
