Workers need to be able to try a protector to make sure it is comfortable for them. There is no way to predict comfort and no substitute for trying them out. Even though every one of these workers knew they were developing significant permanent hearing loss, they were wearing their earplugs only about one-third of the time they were working in noise. These workers then received custom molded earplugs designed to conform perfectly to every nook and cranny of their ears. After they were fit with these custom earplugs, the workers doubled the amount of time they wore their earplugs.
Convenience is key to wearability.
Workers need convenient access to hearing protectors. Employers should make hearing protectors available where noisy work takes place. Unfortunately, many employees have to go to the nurse, the safety office or to a supervisor to pick up new or replacement hearing protectors. Employees won't bother if they are in a hurry or the location of the office is inconvenient. Unless you are replacing expensive hearing protectors or dispensing individually fit earplugs,workers should not have to see a nurse or supervisor to get hearing protection.
