The audio begins with the distinct, resonant sound of a wooden door being shut firmly. The familiar echo of solid wood meeting its frame reverberates through the room. Next, the crisp metallic rattle of a deadbolt lock can be heard, a sound that suggests both security and finality. The key is inserted, and the lock mechanism is engaged with a satisfying click, indicating the successful securing of the door. The metal deadbolt sliding into place against the wooden door creates a comforting sense of safety and closure. The audio ends with the faint, retreating footsteps, leaving behind the silent assurance of a door securely locked.
