Dielectric noise blocking earmuffs guard hearing from hazardous noises generated by equipment in the workplace. The personal safety gear is designed with an excellent sealing capability with colour options for rapid compliance checks.

Noise blocking earmuffs provide the best attenuation and noise reduction rate levels for all frequencies.
