EB15 is for persons who operate some or most of
the time around continuous loud noise such as
machinery, trucks, or construction equipment and
want both blast protection and natural hearing when
no background noise is present.
Both versions use a new adaptation of the original
high-fidelity K-AMP
® integrated circuit. The EB1
permits natural hearing until a blast occurs. EB1 has
a switch to boost faint sounds if desired. EB15
circuitry is configured to protect the user in loud
continuous noise from machinery and vehicles and
from unexpected impulse noise such as gunfire and
explosions. When no loud noise is present, the EB15
returns to natural hearing, as if nothing is in the ear
to block sound. The EB15 also has a switch to boost
faint sounds.
With practice, most users should experience normal
situational awareness: Normal detection and normal
ability to determine where a sound is located.
