MSA Supreme Pro-X: Hearing Protection with Situational Awareness

摘要

Hearing protection is of paramount importance, since lost hearing cannot be recovered. Typical gunfire measures 150 to 160 decibels, with 140 decibels being the commonly accepted threshold for hearing damage. Cost-effective and readily available foam earplugs provide some attenuation, but that alone may be insufficient (Ylikoski et al., 1995). In addition, environmental factors such as an overhead awning or a barricade can cause reverberations and amplify noise to unsafe levels.
