Brief Door Knocking Sound

A brief but clear knocking sound can be heard, instantly recognizable as a rhythmic tapping on a wooden surface. The distinct resonance suggests it's coming from a wooden door. It's a classic door-knock, a sound that seems to echo in a quiet home or perhaps an empty corridor. The sound is not too loud or too soft, but just right to catch attention. The knock is not hurried or frantic, rather it's a calm and steady knocking on the wood door, leaving an air of anticipation for whoever might be on the other side. It's a simple, everyday sound, yet it carries a sense of mystery and expectation.
