Moldex has announced a new formulation that achieves an NRR 33 for its SparkPlugs®, Pura-Fit®, Camo Plugs® and Softies® brand foam earplugs. Moldex’s NRR 33 is the highest independently tested NRR on the market, the company reports. The higher NRR is the result of a new softer foam that increases the comfort of the already soft earplugs.Moldex-Metric, Inc., Culver City, CA. AIHCE BOOTH 609
