With louder and louder weapon systems being developed and military personnel being exposed to steady noise levels approaching and sometimes exceeding 150 dB, a growing interest in greater amounts of hearing protection is evident. When the need for communications is included in the equation, the situation is even more extreme. New initiatives are underway to design improved hearing protection, including active noise reduction (ANR) earplugs and perhaps even active cancellation of head-borne… 

Hearing Protection for Bone-Conducted Sound

The aim of this investigation was to characterise the transmission levels of bypass sound to the cochlea and to determine the effectiveness of different hearing protection components in attenuating this sound.

Sound attenuation from earmuffs and earplugs in combination: maximum benefits vs. missed information.

Sufficient low-frequency attenuation may be achieved with muffs and plugs in combination to prevent hearing loss from operational noise and choose a smaller earplug to achieve a better fit.

Investigating Double Hearing Protection using Human Subjects

From direct measurements of the Sound Pressure Level under the earmuffs during the MIRE procedure, it can be concluded that the attenuation of the earMuff remains constant, implying that there is an interaction between earmuff and earplug that is leading to the degradation of the attenuations afforded by the double protection system.

Effectiveness of hearing protector devices in impulse noise verified with transiently evoked and distortion product otoacoustic emissions

Findings suggest that the HPDs are able to prevent cochlear damage, and both types of OAEs were evaluated in subjects before and after exposure during a five-day military practice.
