The Introduction of Custom Earplugs Aboard LCS-1
Abstract
NSMRL was responsible for providing custom-molded hearing-protective devices (HPDs) and conducting advanced hearing-conservation efforts with the crew of USS FREEDOM (LCS-1) as part of a longitudinal study on the effectiveness of a hearing-conservation program. This report documents our relevant experience with LCS-1 crewmembers, discusses related reports on the use of foam and custom HPDs, and provides interim recommendations. Custom-molded HPDs were judged by users to be superior in comfort, and able to be worn for longer periods of time than other devices (foam). Based on data from LCS and other related studies, the performance, acceptance, and cost of the custom-molded product are comparable, or better, than foam HPDs. The interim recommendation is to provide multiple types of HPDs, including custom earplugs, to service members.
