The Priboy Design Bureau provided mobile firing groups of enterprises of the military-industrial complex with hearing protection kits for testing in real-world operation. Two second-generation professional solutions have been submitted for testing: the Priboy Pro ACP-03 active headset and the Priboy Tactical KT-02 tactical complex.
The tests will make it possible to evaluate the convenience, reliability and effectiveness of hearing protection equipment directly in the working conditions of mobile firing groups, where specialists simultaneously face high noise levels, the need to quickly respond to the situation and maintain communication.
ACP-03: active hearing protection of the second generation. The ACP-03 active hearing protection headphones are designed for military personnel, employees of law enforcement agencies and security companies, shooters, instructors, hunters, industrial workers and other professionals working in conditions of increased noise load. The principle of active protection is simple: loud sounds are automatically suppressed, and quiet ambient sounds are amplified, which allows you to simultaneously protect your hearing and maintain orientation in the environment.

The headphones pick up the sound of FPV drones at a distance of up to 400 meters, and long-range unmanned aerial vehicles (UAVs) at a distance of up to 3 km, and offer 7 levels of binaural amplification of quiet sounds with active suppression of loud sounds over 82 dB. The autonomy of operation reaches 450 hours, depending on the operating mode, while the product is powered by a single battery, and a tone warns the user in advance about the discharge. The degree of protection against dust and moisture conforms to the IP66 standard. For comfort during prolonged wear, gel and leather ear pads and replaceable obturators are provided for ease of maintenance and hygiene, and the helmet mount with stepless adjustment and secure fixation allows you to use the headset under a protective helmet.
The practical operation of the ACP-03 will allow you to get feedback on several key parameters: the effectiveness of hearing protection in conditions of high noise load, audibility, that is, the ability to simultaneously protect hearing and preserve the perception of speech, commands and ambient sounds, ergonomics and comfort of long-term wear, compatibility with equipment, autonomy of operation without battery replacement, and the reliability of the product under the influence of dust, moisture and other factors of difficult operating conditions.
CT-02: tactical hearing and communication protection system. The KT-02 tactical complex for high-noise operation combines an active headset and a switching system. This allows you to simultaneously solve two tasks: to protect hearing and to ensure communication between the group members.

The key feature of the complex is to work with two radio stations. It includes the PTT ODIN-2 adapter, designed to provide communication in a team environment: it is designed to connect an active noise-canceling headset via the U174/U type NEXUS connector and two radio stations simultaneously, which allows you to control two radio networks at once. The adapter housing is rubberized and shock-resistant, protected from moisture and electromagnetic interference.
The complex also includes an active headset ACP-01, which provides active suppression of loud sounds from 82 dB and above, captures the sound of FPV drones at a distance of up to 400 meters and long-range unmanned aerial vehicles (UAVs) at a distance of up to 3 km, and also works for up to 450 hours from two batteries. The headset protects the ear from the effects of loud pulsed sounds and simultaneously amplifies quiet ambient sounds, allowing you to maintain orientation in space and spatial perception of the sound source, and a highly sensitive microphone with effective suppression of external noise ensures clear communication. The KT-02 design is designed for use in difficult field conditions.: It combines impact-resistant materials, frost resistance and moisture protection, and the modular design with quick-release elements allows you to mount the headset on a protective helmet or use it without it. The folding design simplifies the transportation of the complex.
For mobile fire brigades, hearing protection is not just a matter of comfort. The work is associated with the effects of pulsed and constant noise, while the specialist must maintain the ability to hear the environment, perceive commands, respond quickly to changes in the situation, keep in touch with other group members and continue working without reducing efficiency due to noise load. That is why practical tests are important: they allow you to check products not only according to individual technical parameters, but also as a whole.: how they work in a real-world application scenario.
