Hearing Protection and Recreational Earpieces

Custom-fit earpieces for communication or hearing protection provide consistent fit. Users can take advantage of custom-fit earpieces for a variety of applications, whether it's swimming, listening to music, shooting, or motor sports. Tests conducted by the United States Air Force Research Laboratory suggest that participants who wear custom-fit hearing protection experience a greater consistency of fit and attenuation than those using generic over-the-counter products.

SPECIAL NOTE: Care should be taken when looking at the attenuation factors for earmolds that are not rated. Not rated earpieces are for comfort (reduce noise from snoring) or for custom fit earmolds for earbud or in-ear monitor plugs. They should not be used as hearing protection from loud environments that OSHA requires employees to wear hearing protection.
