Place it at the start of a mic-fail moment, right after the Classic Error Sound marks the problem, then let the Bell Ding Sound Effect signal that the microphone is ready again before the speaker begins.
关于此声音
This is a 4.7-second sound effect of a microphone being fixed, with handling and adjustment noises as someone works to get it ready to speak into. It feels awkward and familiar, like the small technical pause before a call or recording finally starts, and it works because almost everyone has waited through a moment like this.
