Bahn is a very short, under-half-a-second sound built around its single name, delivered as one abrupt burst that lands and ends before a listener can settle into it. The brevity gives it a sharp, startling jolt, like a cue dropped into a conversation to cut through the noise and reset the moment. It works best as a quick interruption rather than a sound to linger over.
