Heartbeat effects like this are widely used in horror and suspense audio packs rather than being tied to one famous scene. This clip is credited to Spooky Tales And Scary Sounds, which fits its scary, cinematic style. Online, creators use heartbeat audio to signal fear, rising panic, or a dangerous moment just before impact. It remains popular because the sound is instantly understood by viewers and can make even a simple visual feel more urgent, uneasy, and emotionally loaded within a few seconds.
