Crescendo Impact 20

Nail guns, riveters and drop hammers all produce impulse noise up to 150 dB, which can critically and permanently damage hearing. Crescendo Impact protects users hearing against these sounds by using patented filter technology by Dynamic Ear Company, that is ANSI IPIL certified to protect against impulse noise of up to 166 dB, providing optimum protection from high impulse and impact noise made by nail guns and hammering.
Impact ear plugs reduces the sound level by 20dB making it safe for 8 hours continuous use in any environment up to 100dB. The small size is unobtrusive, fitting easily under earmuffs where double protection is required.
