Tactical Communications Headset Product

Overview

A tactical communications headset solves two contradictory requirements at once: it must protect hearing against gunfire — impulses of 150–170 dB peak that destroy cochlear hair cells instantly — while preserving and even enhancing the quiet sounds, speech, and directional cues a soldier or police officer depends on. Passive earplugs do the first and ruin the second. The electronic talk-through headset, now standard issue in most NATO armies, does both, and adds the third function of connecting the wearer to one or two tactical radios.

The architecture is a sealed passive attenuator with an electronic bypass. The Earcup Pair blocks everything; the Talk-Through Electronics electronics reproduce the outside world inside the cups at a controlled, never-dangerous level.

Hearing protection and talk-through

Passive protection comes from the sealed Cup Shell and Ear Cushion, typically rated 20–26 dB SNR under EN 352. The seal is the weak point in practice: eyewear temples and helmet straps break it, which is why gel cushions that conform around glasses matter more to real-world attenuation than the rated number, and why the Hygiene Kit exists to replace cushions as the foam compresses with months of wear.

The talk-through path runs from four externally ported Ambient Microphone — two per cup, placed to preserve the interaural cues the brain uses to localize sound — through the DSP Board to a Speaker in each cup. In quiet, the system passes ambient sound at unity gain or amplifies it up to four times, restoring the awareness the passive seal removed; users routinely hear better with the headset than without. When a gunshot arrives, fast-attack compression clamps the reproduced level within about 2 milliseconds, holding output near 82 dB SPL no matter what the microphones saw. Unlike old peak-clipping designs, compression keeps speech intelligible through sustained fire instead of chopping the audio to silence. Foam Microphone Windscreen keep wind roar from masking the quiet end of the range.

Radio communications

Transmit audio comes from the Boom Microphone. Its Microphone Capsule is a dual-port differential element: pressure arriving from far-field noise hits both ports nearly equally and cancels, while close-talked speech from 3–5 mm away drives the ports unequally and passes. This is what keeps voice intelligible from inside a moving armored vehicle or beside a running helicopter at over 100 dB ambient. The Boom Arm holds the capsule at the corner of the mouth through recoil, and the Boom Hinge lets it swap sides or stow upward.

Keying happens at the chest-mounted Push-to-Talk Unit, connected through the Downlead Assembly and terminating in a Radio Connector — the NATO U-174/U or the 6-pin MIL-C-55116 — with a radio-specific Radio Cable matching whichever radio family the unit fields. Dual-comm variants run two nets to the two ears with separate PTT Switch keys, letting a team leader monitor the squad net in one ear and command in the other. The PTT lives in an IP67 PTT Housing clipped at a fixed, memorized spot on the plate carrier so it can be keyed without looking.

Wearing it

The Spring Band sets clamp force in the 8–12 N window — enough to seal, tolerable across a 12-hour shift — with a Cup Yoke giving each cup height and tilt adjustment. Low-profile shells are cut so a rifle stock cheek weld does not lever the cup off the head. For helmet users, Helmet Rail Adapter move the cups onto the ballistic helmet's ARC rails, deleting the headband entirely and letting the cups swing clear when not needed.

Power is deliberately boring: two AAA cells in a sealed Battery Compartment run the electronics for 300–1,000 hours, helped by the Power Board's automatic shutoff after a few idle hours. Even fully dead, the headset keeps working — the passive attenuation and the wired microphone and speakers need no power, so a flat battery costs situational awareness but never hearing protection or comms.
