<abstract displayLabel="Summary">Hearing protection devices are tested for their attenuation characteristics under controlled laboratory conditions. Unfortunately, these tests overestimated the typical attenuation performance of the devices in the field, posing the possibility of inadequate protection for the user. Many factors may affect achieved in-field attenuation. This research investigated the influence of the user's work-related movement and variations in headband compression force and earcup cushion material on the frequency-specific noise attenuation achieved with earmuffs. The resulsts indicate a small effect of moderate physical work activity on hearing protector effectiveness and illustrate the importance of certain earmuff design parameters to achieved attenuation</abstract>
