Hybrid Push-In Style Ear Plugs: Factors that contribute to a proper fit and long-term comfort

Experts realize that most foam ear plug users do not properly fit their ear plugs and often compromise hearing protection for personal comfort. Meanwhile, hybrid push-in style ear plugs combine foam with an insertion aid, such as a stem, to eliminate the need for roll-down and provide a quicker, easier fit. 

This white paper discusses benefits of the hybrid push-in foam style in terms of fit, use, comfort, and hearing protection. It analyzes several models of hybrid ear plugs in terms of material and stem composition, design, and Foam to Stem Ratio (FSR) – as well as the levels of attenuation and variability of fit achieved by untrained users.
