The Elvex Blue™ disposable foam ear plugs have been redesigned and retooled. The most obvious change involves the shape, which is more tapered and the softness of the foam. As a result of the new shape this new generation of ear plugs is easier to insert correctly, and this in turn has resulted in a significant improvement in the Noise Reduction Rating to 32 dB. The high visibility blue color also makes it easier to monitor compliance. In summary these are the benefits:• Unique ergonomic shape• Softer foam• Slower expansion for easier insertion• Higher NRR• High visibility color• Better user acceptance
