Frequently Asked Questions

Q: Which provides better noise reduction - earmuffs or earplugs?

A: Generally, earmuffs offer slightly higher attenuation than earplugs, but this depends on specific models. Earmuffs are suitable for extended, stationary work; earplugs are better for hot environments or when wearing other head protection like hard hats.

Q: Can they be worn together with earplugs?

A: Yes. In extremely high-noise environments (above 100 dB(A)), wearing both earplugs and earmuffs provides double protection with combined attenuation.

Q: How to clean and maintain?

A: Wipe the shell and cushions with a damp cloth to remove dust and dirt. Avoid strong acids or alkalis. Store without heavy pressure to prevent deformation.

Q: What is the service life?

A: Service life depends on usage frequency and environment. Cushion material hardens with age; inspect every 6–12 months and replace if showing significant aging or damage.
