This sound is the widely recognized crickets chirping gag used in comedy editing to represent silence, awkwardness, or a room going dead. It does not depend on one specific movie or meme source, which is part of why it spread so widely across radio jokes, TV comedy, YouTube edits, and short-form videos. Creators still use it because the meaning is immediate: when the chirps appear, the audience understands that nobody responded, nothing landed, or the moment became painfully quiet.
