Professional hearing protection for defence operations
Tactical hearing protection against impulse and continuous noise without compromising communication, situational awareness and operational compatibility.
Dynamic Ear Company has been active in the defence sector since 2014, with its impulse protection technology originating from product developments for a British Ministry of Defence tender. The patented impulse protection system is deployed by defence organisations in Europe, including the Dutch and Spanish MoD, and is currently under evaluation in more countries. Today, the technology is brought to market under the DYNAMIC ear filter brand as Technical Impulse Hearing Protection Multimode (TIHP Multimode), covering both impulse and continuous noise attenuation.
Operational requirements in defence environments
From training ammunition to artillery, DYNAMIC ear filter solutions are designed for defence environments in which impulse, impact and continuous noise occur in parallel and vary in intensity and duration.
This military hearing protection provides controlled attenuation across these conditions while maintaining communication, situational awareness and compatibility with operational equipment, for example with over the ear communication systems.
This is achieved through the following system characteristics:
Maintains situational awareness
Preserves directional hearing and spatial perception, enabling early detection of relevant sounds and maintaining orientation in dynamic situations.
Attenuates impulse and continuous noise
Attenuates sudden peak noise such as gunfire and explosions while maintaining continuous attenuation in noise environments like vehicles and aircraft.
Supports communication
Allows speech to remain intelligible within communication systems, avoiding the loss of coordination typical of full-block or foam-based solutions.
Designed
for long-term
operational use
Allows airflow in the ear canal, reducing heat and moisture build-up while maintaining a stable fit during movement and extended use.
Integrates with
helmets, headsets
and double protection
Low-profile in-ear design prevents mechanical interference, friction noise or pressure when used under helmets and in combination with over-ear systems.
Battery-free,
uninterrupted
operation
No removal or manual adjustment required during changing noise conditions, avoiding handling complexity and always ensuring consistent protection.
Noise exposure in defence environments
Impulse noise in defence environments ranges from low-level training ammunition to high-energy events such as grenades, flash bangs and artillery systems, with even training scenarios such as FX ammunition producing sound profiles comparable to live fire. Continuous noise is present in vehicles and aircraft, including armoured vehicles, helicopters and engine-driven systems, often under enclosed and reverberant conditions. Military engineering and technical tasks introduce additional impact noise through metal-on-metal work, pneumatic tools and structural activities.
DYNAMIC hearing protection for military use is built for these conditions. They protect against impulse, impact and continuous noise while preserving communication and situational awareness across the following operational scenarios:
Training and live fire
FX ammunition, live fire, grenades and artillery
Vehicles and aircraft
Armoured vehicles, helicopters, engines and enclosed environments
Engineering and technical tasks
Pneumatic tools, scaffolding, bridge construction, metal structures
Workshops and maintenance
Mechanical work, repair activities and tool-related impact
Standards, testing and manufacturing
DYNAMIC ear filter tactical hearing protection systems are developed for defence use, with consistent performance and verified protection.
Made in Europe
DYNAMIC military hearing protection is developed, manufactured and tested in Europe. Engineering, production and acoustic validation are carried out in the Netherlands, providing full control over product quality, traceability and performance across all stages.
Acoustic testing
Each product is individually tested to verify its attenuation. Performance is measured for every product rather than assumed from batch testing. This ensures consistent and repeatable performance across large deployments.
Certifications and compliance
- PPE Regulation (EU) 2016/425 – Annex VIII, Module D
- EN 352:2020
- ANSI compliance, including ANSI IPIL
- ISO 9001 (Development, Production and Sales)
Industry expertise
Dynamic Ear Company is founded in 2008 and since 2020 part of the Sonova Group. Sonova includes brands such as Phonak, known for hearing instruments and communication systems used in professional and defence environments.
