In the audio titled "Tap 2", the primary sound is of a faucet being turned on, causing water to flow out steadily. The water gushes out powerfully at first before it stabilizes into a steady stream. It hits the bottom of the sink, creating a rhythmic, splashing melody. The echoey acoustics of the sink enhance the serene quality of the flowing water. The sink, likely made of metal, resonates with the impact of the water, creating a subtle, metallic hum that underlies the main sounds. The audio concludes with the sound of the faucet being turned off, the water flow gradually diminishing until it stops completely.
