OTTO Introduces NoizeBarrier High Definition Electronic Earplugs

Carpentersville, IL (May 10, 2017) – OTTO Engineering, an industry leader in the design and manufacture of two-way radio accessories for industrial, public safety, and military applications is pleased to announce the launch of its new NoizeBarrierTM High Definition Electronic Earplugs.


The NoizeBarrierTM earplugs are an essential component for military and law enforcement professionals in the war against hearing loss and for preserving situational awareness during missions. OTTO’s dual-mode electronic earplugs offer active hearing protection as well as a hearing enhancement mode that provides extreme sound localization and detection. The noise-isolating ear tips combined with proprietary sound processing electronics enables the NoizeBarrier earplugs to respond to the user’s unique sound environment. The earplugs provide excellent situational awareness when sound levels are safe, up to 15 dB of protection when there is sustained loud noise, and up to 40 dB of protection from loud impulse noises such as blasts and gunfire.

With a simple press on the touchpad, the enhanced hearing mode feature is activated providing up to 5X amplification of softer sounds, while still maintaining impulse noise protection. Built-in Accu-Technology® brings high-definition sound quality to the user experience via the balanced armature speakers and the use of wide bandwidth, low-noise MEMS microphones. All of this is accomplished while maintaining natural hearing at safe sound levels for unsurpassed situational awareness and communication.


Using the NoizeBarrierTM earplugs is easy with the one-button touchpad operation and up to 16 hours of continuous use on a single charge. The earplugs can be stored and charged in the rugged carrying case. Both the earplugs and charging case are IP67 water resistant to survive the elements.

The compact storage case serves double-duty as a carrying case and a charging station. The storage case itself can be charged with the provided USB cable. Once charged, the built-in charging station has the capacity to recharge the earplugs up to 20 times, before the charging station needs to be recharged. The inside of the case has a LCD screen to display the charging status of the charging station as well as the battery capacity of each electronic earplug. The combination of rechargeable earplugs and the portable charging station make the NoizeBarrierTM earplugs ideal for extended and demanding missions.

OTTO’s NoizeBarrierTM High Definition Electronic Earplugs come equipped with one pair of electronic earplugs, an assortment of ear tips, replacement ear filters, a cleaning tool, USB charging cable, a storage/charging case, and a user manual.

    Very similar concept to 3M TEP-100.

  2. TominVA says:

    Interesting, but 16 hours on a charge. Not for extended operations beyond the FOB then.

    • Greg says:

      It does say the case can recharge the earplugs 20 times though, so 320 hours, or 13 1/3 days of use before you need to find a power source.

    Couldn’t find them on their website. Maybe I’m looking in the wrong sections.

    Being noise cancelling, I don’t think these would be appropriate for an autistic person with noise sensitivity to children and dogs as they are intermittent, not like the constance of machinery. Am I right?
