3M™ Combat Arms™ Earplugs –
3M™ Combat Arms™ Earplugs – Generation 4.1 meet the demanding hearing protection needs of those serving in the armed forces and defence markets. Rest assured, 3M strives to protect the hearing of those who protect us.
When do I set the rocker switch for either Open Mode or Closed Mode?
If you are firing a weapon (in training or in combat) and you have to maintain situational awareness and hear verbal communication, set the rocker switch in the Open Mode. In all other situations, including for steady/continuous noise (such as in a helicopter or tracked vehicle), set the rocker switch in the Closed Mode. Noise from weapons fire (i.e., impulse noises) will be attenuated in either mode, but only the Closed Mode provides protection from other noise, such as continuous noise.
How do the Combat Arms Earplugs protect my hearing from weapons fire or explosions in the Open Mode?
Impulse noise must pass through an acoustical filter. This acoustical filter reacts to sudden, loud sounds such as weapons fire. The louder the sound, the greater the response. In quiet, the acoustical filter allows sounds to pass through with as little reduction as possible.
How do I determine the correct size?
It is essential that someone with the appropriate training fits you
with the correct size. Sizes are color-coded – small (green), medium (tan) and large (brown). The three pronged sizing tool may help provide an approximation of the correct size, but the insertion of a trial earplug is needed to confirm. Approximately 1% of people will require a different size in each ear.
What is the best way to clean the earplug?
Use plain soap and water only, no harsh chemicals or detergents.
Ensure the soap is thoroughly rinsed off so no holes are clogged.
For best results, separate the plug from the plastic housing and
clean the plug separately.
How do I know when to replace the Combat Arms Earplugs?
Replace if there are tears or cracks under any of the three flanges
or if the plastic housing is damaged.
How should I store the earplug?
When not in use, keep in the plastic case provided or tie the cords
to the helmet webbing for quick access.
Are any other modifications to the Combat Arms Earplugs recommended?
None are recommended. Any other modifications or alterations
could invalidate CE approval or degrade the ability of the earplug to protect you from hazardous noise and/or interfere with your ability to maintain situational awareness and hear oral communications.
