Put this clip at the start of a search scene, just before the person being called appears on screen. Follow it with the Ceeday Huh sound, then the Oh My God Wow sound once Jaap finally shows up, so the sequence moves from calling out to finding him.
关于此声音
This is a half-second voice clip of a single spoken word, 'Jaap?', delivered as a short, rising question. It sounds like someone calling out to a person of that name and waiting for a reply. The effect is puzzled and lightly comic, a quick check-in that feels curious rather than urgent, and it works best as a tiny interruption when that name is mentioned.
