Exposure to hazardous noise is one of the most common occupational risks, both in the US
and worldwide. Repeated overexposure to noise at or above 85 dBA can cause permanent …

Animal studies demonstrate that noise exposure can permanently damage the synapses
between inner hair cells and auditory nerve fibers, even when outer hair cells are intact and …

Objective: Short-term noise exposure that induces transient changes in thresholds has
induced permanent cochlear synaptopathy in multiple species. Here, the literature was …

In animal models, prolonged exposure (2 h) to high-level noise causes an irreparable
damage to the synapses between the inner hair cells and auditory nerve fibers within the …

Introduction Injuries to the peripheral auditory system are among the most common results of
high intensity impulsive acoustic exposure. Prior studies of high intensity sound transmission …

Animal models suggest that cochlear afferent nerve endings may be more vulnerable than
sensory hair cells to damage from acoustic overexposure and aging. Because neural …

Objective: This research assessed the reduction of peak levels, equivalent energy and
sound power of firearm suppressors. Design: The first study evaluated the effect of three …

Objective: The objective of this study is to determine whether acoustic reflexes are pervasive
(ie known with 95% confidence to be observed in at least 95% of people) by examining the …

Noise-induced hearing loss (NIHL) is a major problem for active duty service members and
veterans, as well as civilians. As per the preface to this special issue, the development of …

The current study addressed the existence of an anticipatory middle-ear muscle contraction
(MEMC) as a protective mechanism found in recent damage-risk criteria for impulse noise …
