We-e-e-e-ll, no I haven't been to Jamaica, but I doubt that a mountain bike track with pigs running across it has traffic noise exceeding 80 dBA which is what's street legal for a single vehicle at low RPM, never mind illegally modified exhaust systems, revving motors, or the collective noise of hundreds of vehicles at once.

And if you don't protect your hearing when you're in traffic and wind up with severe hearing loss, then you'll hear even less of your surroundings.
