This is a 14-second prank effect combining a clear knock knock on a hard surface with a blown-out, distorted bass burst that takes over the audio. It feels startling and silly at once, turning an ordinary knock into an exaggerated interruption that listeners instantly read as a joke rather than a real visit.
