1. Hearing loss is cumulative and once lost, can never be regained. The best way to protect your hearing is to create a habit of wearing comfortable hearing protection. Earmuffs must fit tightly and comfortably over the ears so that sound is blocked from entering the ears. Handgun and rifle shooters who need maximum hearing protection should use a full cup design, while shotgun shooters tend to prefer a low profile cup because the design does not interfere with the mount of their gun and still provides a high level of hearing protection.
