As the audio begins, you hear the faint sound of bubbling water in the background, growing louder with each passing second, evoking the image of a tea kettle sitting on a stove. The gentle hiss of steam escaping gradually builds up, hinting at the rising temperature within the kettle. Suddenly, a high-pitched whistle breaks the tranquility, growing steadily in volume. It's the unmistakable sound of a tea kettle's signal, announcing that the water has reached its boiling point. This sound continues for a few more seconds before gradually fading away, leaving behind the comforting aura of a hot, freshly brewed cup of tea awaiting to be poured.
