The audio begins with the distinct sound of water rushing into a bathroom drain. It starts as a gentle trickle, the liquid cascading into the tube, subtly at first. The pace gradually increases, and the sound amplifies as the water flow intensifies. It's a steady, rhythmic hum, much like a tranquil symphony, as the water seamlessly navigates its way through the drain. The gushing sound of the water is soothing, almost hypnotic, as it continues to flow, creating an echoey resonance that defines the acoustics of a bathroom. The sound of the water subsides gradually, evoking a sense of calmness. The last drops of water can be heard plopping, marking the end of the water's journey down the drain.
