The contributions by Ross Gardner, Jr. are still found in 3M Peltor Earplugs today and continue to provide an exceptional combination of comfort and attenuation in hearing protection. Today, the line has been expanded to include various sizes and shapes of foam, pre-formed and noise-activated earplugs.
