Rapping on an interior door

As the audio experience begins, the rhythmic rapping of knuckles against a door fills the space, creating a rhythmic, almost musical tune. The door, made of wood, resonates with a rich, deep tone; each knock echoing through the room. The wood, perhaps a sturdy oak or a dense maple, offers a unique timbre to each knock - a testament to its solid quality. The sound reverberates, bouncing off the wooden plank construction of the interior, creating an intimate, enclosed atmosphere. Each subsequent knock seems to build on the last, generating a rhythm that feels almost like a heartbeat, steady and persistent. The knocking continues, a constant in this symphony of sounds, painting a vivid picture of an interior door awaiting someone's attention.
