Built for high-noise, high-demand environments. CMR-D helps organizations source helmet solutions built around extreme operational needs.
Flight decks, industrial sites, and specialized operations place people in conditions where noise, communication, and safety all compete for attention. CMR-D's helmet platform is built for teams that need dependable protection without losing the ability to work, and communicate.

Commercial helmet configurations use the same hearing protection technology, the same production tooling, and the same AS9100-certified manufacturing system and process pedigree that CMR-D applies to its most demanding defense work.

The hearing protection architecture was developed and matured for crews exposed to some of the loudest environments on earth, and refined through years of field feedback in environments where protection, communication, and awareness all matter at once.

A high-performance helmet platform for specialized, high-noise, or communication-sensitive environments. Available in standard and communications-integrated configurations depending on the application.
Head protection rating for top and lateral impact, with Class G electrical performance.
Noise Reduction Rating achieved when the helmet is worn with plugs.
Built under the same aerospace quality system that governs our defense-program work.
Measured decibel reduction across frequency bands versus leading earplugs, earmuffs, and hearing helmets, with and without plugs.
Designed for environments where noise exposure is a constant operational challenge.
Configurations can support communication needs for teams that must stay connected in active environments.
Helmet solutions should support the wearer through demanding work, not distract from the work itself.
Designed for specialized environments where equipment needs to hold up to real operational conditions.
CMR-D helps you identify which helmet configuration fits the application, including visor options, accessories, radio and comms integration, and mounting needs.
“In my 35 years of working on and isolating pipelines… I have never been able to stay at the blowdown valve more than a few seconds. During this blowdown I had to stay for a few minutes. The only reason… was due to the fact that I had the noise reducing helmet. I only wish that we could have had this safety item when I went to work 35 years ago.”
“The noise insulation, subjectively, is at least two times better than the Peltor X5A + earplugs combination… It would not be unbelievable to me that the HGU-99 has achieved, for practical intents and purposes, the ceiling for noise isolation.”
“The [helmet] reduced the sound to where I felt comfortable being there where I would have otherwise left immediately… [it] is the best hearing protection there is.”
“I am already convinced of it's unmatched superior sound protection for people with hyperacusis in high decibel environments.”
“The fit is perfect. It cancels out all harsh sound.”
