Applause is basically a synchronized pulse that everyone in the room contributes to; when the timing is spot on it aligns the crowd’s internal rhythm with the performer’s, creating a small, collective resonance. The “electric” feeling comes from that brief spike in dopamine when the audience’s pulse matches the expected beat—like a tiny, consensual handshake in which everyone says “good job” simultaneously, but without the awkward small talk. It's less about the sound and more about the shared temporal agreement.
