The audio begins with the distinct sound of a hand rhythmically rapping against a wooden surface. It’s unmistakably the sound of someone knocking on a wooden door. The knocks are firm yet respectful, echoing slightly as they reverberate through the solid wood. Each knock is distinct, separated by brief moments of expectant silence, like a pause in conversation. The sound is sharp, resonant, and carries the unique texture only wood can produce. This gives an impression of a traditional, sturdy wooden door being knocked upon, perhaps in anticipation of a response from the other side. The series of knocks continues, painting a vivid picture of a visitor patiently waiting, or perhaps an urgent message being delivered. The sound concludes with a final knock that leaves behind a lingering echo, like a question hanging in the air.
