How loud is this horn and when should I use it?

The horn is rated up to 600 dB peak sound output thanks to upgraded compressor and large coils, producing an unmistakable train-like tone that cuts through traffic and ambient noise. Use it when you need an immediate, highly noticeable audible warning—such as on highways, in industrial sites, or when maneuvering large vehicles.
