关于此声音
Lean is a short sound effect, lasting 626 milliseconds. The facts supplied give its name and length only, with no description of its tone, voice, or recording, and no confirmed source or origin. Its feeling therefore remains undocumented, rather than described from the title alone. It is presented here as the named effect, without added context.
