关于此声音
This is a short sound effect clip lasting just under two seconds, built around a single brief burst that lands and ends quickly. It gives a listener a small jolt of surprise, the kind that works best as a quick reaction rather than a long moment. Its brevity keeps the focus on the instant it marks, so it fits a joke, a reveal or a sudden change.
