In the world’s most extreme environments—whether icy Arctic waters, turbulent seas, or combat zones—clear communication is the key to mission success. Danish company INVISIO, a leader in advanced personal communication and hearing protection systems, is helping military and security forces around the globe maintain seamless contact in these challenging conditions.

Founded in 1999 and rooted in Denmark’s “Danish Sound” industry cluster—famed for its expertise in acoustics and hearing technology—INVISIO designs systems that enable users to maintain safe and effective communication in even the harshest conditions.

Today, INVISIO focuses exclusively on professional users, primarily within the public sector, supplying military, law enforcement, and security agencies worldwide. What sets the company apart is its ability to combine expertise in human hearing, sound engineering, electronics, and rugged mechanical design to deliver fully integrated communication solutions.

Its headsets and control units provide not only clear sound and hearing protection but also maintain full situational awareness—a key factor in environments where split-second decisions are required.

The challenges of maritime and sub-Arctic environments

Few environments test communication equipment like maritime operations. Units may be required to transition rapidly between platforms—vessels, helicopters, land vehicles—while remaining in constant contact. Saltwater, freezing temperatures, vibration, and submersion all pose serious challenges.

Consider Special Operations Forces (SOF) operating in Arctic waters. Moving from a heated environment to -40°C outdoor conditions can cause condensation to freeze inside conventional equipment, rendering it useless. Similarly, a unit dismounting from a fast boat, conducting a surface swim, and transitioning to land requires robust, reliable communication.

INVISIO’s systems are engineered specifically for these demands. The INVISIO Intercom system enables crystal-clear communication between boat crews and gives them full control of onboard radios and communication devices.

Designed to military standards, the system is submersible to 2 meters and can withstand the harshest shocks, vibrations, and saltwater exposure. This ensures seamless communication even in the most difficult scenarios. And in 2025, INVISIO will introduce wireless capabilities to the intercom, offering even greater mobility and freedom for users.

Complementing the intercom is the company’s T7 headset, a patented, lightweight design submersible to 10 meters. Its advanced push-to-talk (PTT) units function at depths of up to 20 meters, allowing users to maintain clear communication whether they are on a vessel, swimming to shore, or operating on land.

Real-world testing speaks volumes: Zodiac Hurricane boats equipped with the INVISIO Intercom and T7 headset have demonstrated excellent speech clarity even when traveling at high speed in strong winds.

Simplifying operations, enhancing focus

Another standout feature of INVISIO’s approach is flexibility. Its INVISIO Control™ app allows users to set up and manage their systems before a mission or adjust settings on the fly. The app offers a clear overview of communication setups and audio controls, which is particularly valuable during complex operations.

Moreover, the app can be integrated as an API into existing marine systems. In collaboration with SeaCross Marine, INVISIO has embedded its control features into advanced high-speed marine navigation platforms, reducing the cognitive load on operators and streamlining operations.

An additional operational advantage: INVISIO’s systems are designed for use across all environments—air, sea, and land. This eliminates the need for users to switch between different systems as they move between mission phases, saving time and improving efficiency.

Beyond special forces

While INVISIO’s technology was initially developed with elite Special Operations Forces in mind, its rugged and versatile systems are now widely used across the broader maritime sector.

Naval crews on frigates, helicopters, and other vessels face many of the same communication challenges—whether on an exposed deck or in an aircraft hangar. INVISIO’s solutions help ensure that communication remains seamless and reliable in all of these scenarios.

As the demands on modern naval forces continue to evolve, INVISIO’s commitment to innovation and quality ensures that those on the front lines can always rely on their communication systems—no matter how extreme the environment.
