Introduction
The High-Fidelity Electronic BlastPLG™ Earplug was
developed by Etymotic Research to mitigate hearing
damage and tinnitus sustained by an alarmingly high
percentage of deployed soldiers. Despite risks to
hearing from loud machinery and blasts, most
warriors decline to wear hearing protection because
they find it interferes with situational awareness.
The there are two versions of BlastPLG Earplug, the
EB1 and the EB15. Both versions are designed to
restore sound that is blocked when the ear canal is
sealed. Both allow you to hear naturally, as though
there were nothing in the ear, and both prevent ear
damage from loud impulse noise.
EB1 is a good choice for hunters who want to hear
naturally and be protected from sudden firearm
blasts when there isn’t time to insert hearing
protection. Increased loudness can be selected which
boosts the faint sounds of speech and improves
hearing at a distance. Additional clarity is built in for
high-pitched sounds which are most difficult to hear.
