The DeWalt Train Horn by BossHorn is purpose-built for extreme projection and instant, plug-and-play performance. Hand-assembled from a brand-new DeWalt 20V impact driver and fitted with powder-coated metal trumpets, it delivers an authentic, freight-train tone you can feel.
The Quick Answer
In open environments, the DeWalt Train Horn can be heard clearly from up to 1.5 miles. Real-world range varies with surroundings:
- Open fields / water / rural areas: up to ~1.5 miles
- Suburban with light obstacles: around 1 mile
- Urban / high ambient noise: about 0.5â0.8 miles
Why It Carries So Far
- 150 dB output: among the loudest portable air horns available.
- Four precision metal trumpets: deep, resonant tone that cuts through ambient noise.
- High-performance compressor & tuned air path: strong, consistent blasts with excellent clarity.
- Instant power: ready from the boxâjust secure any compatible DeWalt 20V battery (OEM or aftermarket).
What Affects Hearing Distance
- Wind: sound travels farther downwind than upwind.
- Obstacles: buildings, trees, vehicles, and terrain absorb/reflect sound.
- Ambient noise: busy streets shorten effective âheard clearlyâ distance.
- Weather: warm, humid air and temperature inversions can improve carry.
- Elevation & angle: slight elevation and unobstructed line-of-sight help.
Remote Control & Power
Operate the horn wirelessly from up to 160 ft, or upgrade to the long-range remote for up to 2000 ft of control. The remote arrives with pre-installed batteries.
Safety & Responsible Use
- Wear hearing protectionâ150 dB can cause instant hearing damage at close range.
- Mind local noise regulations and avoid enclosed/residential spaces.
- Handheld use: not recommended under a vehicle hood due to heat; if mounting, choose a cool, protected spot (e.g., behind a grille).
- Battery care: disconnect if unused for >5 hours (the remote receiver draws standby power). Store batteries fully charged in a cool, dry place.
Warranty
Backed by a 1-year warranty on the horn gun (batteries/chargers not included).
Bottom Line
Thanks to its tuned trumpets, powerful compressor, and 150 dB output, the BossHorn DeWalt Train Horn can be heard from as far as 1.5 miles in ideal conditionsâdelivering unmatched attention on demand.
